There are those who stand firmly behind the belief that The Simpsons has enjoyed a perpetual purple patch since its inception in 1989; however, there are others, and I belong to this group, who submit that it is a series that underwent a transition around the turn of the Millennium, suffered a dire lull for several seasons in the mid-noughties, before evolving into the show that now, in its twenty second season, continues to entertain audiences of all ages. Season thirteen represents a time when the show was clinging to the classic humour that was derived from situations that were routed in a reality - albeit a heightened reality - which could happen to you and your family, while slowly descending into the surreal and farcical, which now represent the episodes currently being made. The season begins with Tree House of Horror Twelve as would become the customary premier episode the Simpsons annual offering of three ghoulish tales that parody horror movies, featuring the characters of Springfield. The first segment sees Homer run afoul of a Gypsy, who then places a curse on the family, turning them into mythical creatures. To reverse the curse Homer must find a Leprechaun, which leads to the first appearance of the angry, Irish creature that would became a staple from here on. And rightfully so; he is as funny as he is un-PC. The second segment parodies 2001 with Pierce Brosnan giving his best acting turn since The Long Good Friday? He plays the computer that becomes infatuated with Marge and goes on a killing rampage to have her for himself/ itself. Finally there is the Simpsons take on Harry Potter, with good ol Mr. Burns playing the evil Lord Montymort. The series continues in this strong vein with Homer the Moe, where Moe returns to bartending school after losing his passion for the business, leaving Homer in charge. Moe returns with a new lease of life, changing the grungy, down and dirty Moes Tavern into, M, a po-mo, trendy wine bar, that brings him success, but alienates him from his loyal customers and friends. Moe learns you dont know what youve got till its gone. Its an archetypal story told very well and continued to show the strength of the character of Moe, who would go on to be one of the only genuinely funny characters in the following baron years for the show. The celebrity cameos continue thick and fast; Seinfelds Julia Louis Dreyfus gives arguably the best of the season, playing criminal Snakes ex girlfriend turned cop who enters into a January- December relationship with Mr. Burns. While Richard Gere is bland and dreary, he cant ruin a great episode where the towns church burns down, causing the residents to re-examine their faiths. Lisa finds enlightenment and fulfilment in Buddhism, causing Flanders to blurt out the hilarious, My Satan sense is tingling. Then there is 'Weekend at Burnsies, a hilariously daring episode that sees Homer becoming a lord to a murder of Crows, who for a while do his bidding, before turning on him. The resulting injuries lead to him being prescribed medicinal marijuana. Homer high has to be experienced. Apart from being very funny, the episode also manages to make statements about Marijuana, but never becomes preachy. However, for all of these solidly structured, superbly executed and utterly hilarious episodes that resemble The Simpsons in its glory years, there are a number of woefully weak episodes that feel contrived, rushed and handled by hacks. Jaws Wired Shut is a prime example of this; it sees Homer running into a statue of not Mike Tyson Drederick Tatum, and being forced to have his jaws wired shut, consequently learning how to listen and be a better person. Dull. And the Parent Rap, which sees Homer and Bart tethered together by a judge, is an example of the farcical that the series would fall deeper and deeper into. But at least it shows some level of originality. Half Decent Proposal, the episode that saw the return of Marges high school prom date, turned billionaire, Artie, offer the family millions for one night with Marge is an exact rip-off of Indecent Proposal, but somehow manages to be worse that that dire movie. This laziness continues with, yet another Simpsons clip show, which although the producers have made fun of over the years, and this particular one has a Forrest Gump homage present, it cant help but leave you feeling cheated. And Tales from The Public Domain has Homer reading Bart and Lisa three classic stories, The Odyssey, Joan of Arc and Hamlet all featuring members of the Simpson family, of course which has a few laughs, but just feels half-hearted. Perhaps the worst episode in the season, and the one that received the most complaints, not for being poor and contrived, but for its representation of Brazil, is Blame it on Lisa. When Lisas Brazilian pen pal stops writing to her, the family up and head off to Rio de Janeiro money, pet and babysitting plans, inoculations, concerns about travelling to South America are not an issue, and the adventures and situations they find themselves in Homer getting kidnapped by drug lords are too unrealistic and more importantly, lack the humour to get you through. This of course would start the trend of sending the family to every world destination that Americans are sufficiently aware of that humour can be derived from stereotyping and parody. Bad times. However, when The Simpsons producers are on, they are really, really on, and the episode I Am Furious Yellow, certainly is an example of this. While Bart becoming an overnight Internet sensation with an online comic book doesnt feel as rooted in reality as the great episodes, it is consistently hilarious. Homers turn as the Hulk is great, and Stan Lee gives one of the all time great cameos, appearing in Comic Book Guys shop, placing Marvel Comics at the front of all the racks and deterring kids from buying anything un-Marvel: The Thing will fit in your bat mobile, he says, before jamming a Thing action figure into a childs bat mobile toy, destroying it and reducing the child to tears. He then walks away, proudly humming the Spiderman theme. Its just great comedy from start to finish. Ultimately I can accept that any show that has been running for thirteen years count them, there havent been many will struggle to maintain perfection and a cohesive style throughout a whole season. And while The Simpsons, in my opinion, managed that for a number of years in the 90s, the issue of a change in times and values and sense of humour must also be taken into consideration. In this season there are one or two great episodes, many good ones and some that although dont live up to the shows high standards and are still very funny in comparison with anything else you will find. The problem comes from when you started to watch the show. If you were a die-hard follower in the mid-90s you will probably find the change in tone and style far more difficult to come to grips with than someone who became familiar with Americas favourite family far more recently. Either way, theres still enough here to justify adding The Simpsons: Season Thirteen to your library.
