I was unsure about this movie because it never got rave reviews when it first came out but it's so underrated! It's silly fun with a weird alien invasion story, a lot of d*ck jokes and a killer cast! It's written by Seth Rogen/Evan Goldberg (same guys who wrote Superbad) So you should know what to expect. Ben Stiller. Vince Vaughn and Jonah Hill doing what they do best. And Richard Ayoade is one of the most underrated British comics ever. He's awesome in this movie. And the twist in this involving him was great. Even tho i really like this movie it's not a comedy diamond like Anchorman or Step Brothers or some of the other brilliant comedy movies that have came out in the last few years. But it's decent and it's funny. So if your a fan of silly, entertaining, magically funny one liner movies like i am then you'll definitely like this movie.
