Movie Sidekicks Who Actually Did More Harm Than Good

"Superbad" is undoubtedly a funny movie, and the character Seth's (Jonah Hill) lack of likability and competence definitely contributes to its comedy. But in real life, anyone would advise Evan (Michael Cera) to drop such a self-centered, ridiculous friend. Seth spends the entire movie shooting snark at his best friend because Evan has decided to attend a different college than him. At the same time, he makes it clear that his number one priority is getting to a party and having sex with his crush, Jules (Emma Stone). 

Seth promises Jules that he will obtain alcohol for her party and immediately enlists Evan and their other friend, Fogell (a scene-stealing Christopher Minzt-Plasse), into his scheme, putting them both in danger with the law and chaotic people throughout the night. Seth's plan is the main plot line in the film, but if Evan and Fogell had attempted it without him they most likely would have succeeded much more easily. 

When Seth finally arrives at the party and gets to hang out with Jules, he's so wasted that he accidentally headbutts her after she tells him she doesn't want to hook up while he's drunk. Luckily for Seth, she still gives him another chance the next day. What's most upsetting about Seth is that Evan is terrified to tell him that he will be college roommates with Fogell, who is attending the same school as Evan. Seth is so emotionally explosive and self-centered that Evan is literally afraid to share what should be pleasant, or at least neutral, news.
