I've arrived at the conclusion that this is a very well made film. Not your typical alien invasion movie, but instead had a nice purpose for these beings and some plot twists and themes to think about.
Somebody mentions the words "heist film" to you, what did you just think of? That's right, Recess: School's out. A film truly ahead of its time in every aspect of film making. Breaking down stereotypical barriers and changing the movie scene for good, recess takes risks and blows minds in a ways never seen before. The gang is back together led by TJ, the fearless leader and also features the nerd, fat guy, jock, bully, and other nerd. Through the power of friendship and hardwork, they accomplish their dreams and save the world, one playground at a time.
