I must admit that seeing the trailers didn't do anything for me, but decided to give it a go because of the reviews. Should have gone with my gut feeling after the trailers though.
First of all, it is supposed to be a comedy, but it isn't funny at all. I have no idea when you were supposed to laugh. There was nothing new at all, and what there was wasn't done well.
The first hour is just a bunch of people acting like they are all on crack and it is mostly made like tiny montages. And then there is the usual phase where things go a little bad before it is all good again.
84 metascore!? You must be f...king kidding me. I don't even get the user rating. This can only be entertaining if you are 16 and have never seen any movie like this before.
