I was very hopefull for this film, considering the trailers etc. The film starts off very slowly in my opinion and seems to try and say some sort of message (you will know what I mean when you see it)

I'd be lying to say that I enjoyed this film, as I am used to the regular 25mins of simpsons viewing, but the majority of people in the cinema were parents and their kids.
There are a few funny moments and subtle messages around the film with little seriousness which is good, but again it got boring.
All told, in my opinion if you have seen most of the trailers, you have seen most of the film.
I'm sorry to say that I'd be only giving this a 4/10 due to the fact that I have seen the funny moments already.
