10 Movies So Good They Ruined Genres

5. Superbad

2007's Superbad is frequently cited as the greatest teen comedy of the 21st century, and it's incredibly hard to argue with that.

It's a perfect storm of capturing the early-millennial zeitgeist and featuring a largely unknown cast of on-the-rise actors, while melding boundary-pushing R-rated humour with a uniquely affectionate attitude to its characters. In a period where gross-out sex comedy reigned supreme, it was something incredibly fresh and different.

The result was immediately iconic and remains shockingly watchable today, but in the decade since, every single teen comedy to hit cinemas - even good ones such as Easy A and Love, Simon - feels positively pallid by comparison.

Love, Simon might be a wonderful step for inclusion in studio comedies, but will anyone be remembering it with the same reverence as Superbad in another decade? Unlikely.

It's clear nobody expected Superbad to strike as powerful a chord as it did or remain this relevant and quotable in 2018, but the movie's gain is an unfortunate loss for every subsequent teen movie imitation that's followed.
