Mean Girls(2004)
lindsay Lohan stars as Cady, a bit of a naive girl who was previously home schooled in africa. and finds life a lot different when she starts at high school in the US.
and eventually falls in with a group of mean spirited girls known as the plastics who invite her into their clique.
This is one of the best out of all those generic teen comedy type films, and is very funny and well acted, especially by Lindsay Lohan and Rachel mcadams as the meanest girl Regina George. and a very funny performance too from Amanda Seyfried who i recently watched in Ted 2, playing the dim witted plastic Karen Smith.
With witty dialogue and a great screen play by Tina Fey, who also plays a role of a Maths teacher in the film. this is a top recommend, even for guys. 80 out of 100.
