10 Best It's Always Sunny In Philadelphia Episodes
4. The D.E.N.N.I.S System
The evolution of the characters throughout the show has been sublime, but the most entertaining has been the gradual realisation that there may be something far more sinister behind Dennis. Starting as an egotistical narcissist, he at least was able to back it up, as he had tremendous success with people, especially in his love life. However, as the show progressed, we began to see that his methods are not so victimless.
Dennis takes the gang through his six-point system for seduction, which is shockingly controlling. It's the first time we begin to see that the success Dennis has with women is not down to his charm, but rather a frightening system of manipulation. From here on in, we begin to see a darker side to Dennis; questions of having no feelings, an obsession with control, cruel acts toward animals. All of the evidence is pointing towards something unspeakable.
The episode is perfect. It features everything that a strong Always Sunny adventure needs, a good set up, excellent character work, and a dramatic climax featuring the gang misunderstanding everything. Most of all, it gets the ball rolling for the gradual decline of Dennis and makes us fear what he may have in store for us.
