The best part about Green Lantern… oh man, I wish it was on YouTube so I could link you, but I'll just describe it.
Our villain Hector Hammond, as played by Peter Sarsgaard, is a man you cannot help but feel sorry for. His father hates him, Ryan Reynolds has stolen every girl he's ever fancied (or so I concluded, that might be false), he has a receding hairline, some truly unfortunate facial hair, and the one time he gets to do anything cool and performs an alien autopsy, he gets infected with space goo. In short, he is a man Life itself has crapped upon.
Anyway, the space goo gives him powers, as I'm sure we're all familiar with, and he begins to develop telepathy and telekinesis. In the film, his powers first manifest themselves while teaching at what appears to be either a high school or a community college, where all of his students hate him for being pathetic.
In this scene, he has his back to his class when a jock thinks something particularly mean—I forget—and he asks him to repeat it. The jock refuses until, frustrated, Hammond uses his telekinesis to throw him across the room.
Now, this can be done to be honestly terrifying. However, the execution the filmmakers chose to go with was "cartoon ejector seat". It feels like they had to digitally remove the spring and the sound effect, it is that silly.
And that's the only good part of Green Lantern.
