The Godfather 2: Boooring, and it was really mean of Michael what he did to Fredo
The Shawshank Redemption: Pfff, nice guy locked up and becoming mates with his fellow prisoners, laaame.
Citizen Kane: It's not even in color, who am I supposed to enjoy a movie that's all black and white.
The Dark Knight: It's so fecking obvious Bruce Wayne is Batman. Come on. Also, why did he swallow a speech distortion device.
The Original Star Wars Trilogy: Luke Skywalker is such a whiner and the duel between Anakin in Obi Wan in Revenge of the Sith had way more backflips than the one in A New Hope.
On the other hand, all movies with Dwayne The Rock Johnson are massively underrated. Fast and Furious: Hobbs and Shaw is the greatest movie of all time. It has lots of banter, a hot chick and like, 5 explosions per minute.
