First I want to say that I'm not a professional reviewer but I found one review here kinda misleading (after my opinion).
I thought the kind of humor they used in this movie was great! It actually rewards you if you follow the dialogues closely by using "in-jokes". The quality is excellent and the characters fit with the actors really well, so it renders an exclusive atmosphere for the audience.
The overall plot can be predictable, but there's a lot of plot points which makes you unsure about how this all will end.
I would recommend this movie to everybody who feels like they want to watch a good and fun comedy movie. This movie was really enjoyable.
