Films that come from Saturday Night Live actors and writers are structured less on the three-act screenplay than they are on the ever-cascading comedic sketch. Mean Girls (2004) feels like such a film, especially after the denouement that has the head Mean Girl disgraced; and then her retaliation against the ringleader, the "new girl" who takes her place.
What follows from there, with a half hour left in the film, is a massive group therapy session (testimonials, confessions, resolutions) involving all the girls in the school, led by the film's writer and contributing actor Tina Fey.
I have never seen anything like this before (apart from Twitter). After the session, the only remaining tension is "new girl" Lindsay Lohan's sneaking out of the house (from where she is grounded) to compete in the math team's final against a co-ed private school, where she goes one-on-one with the other teams' only girl -- and wins.
