That could be the best movie I've ever seen. Definitely the funniest one I've ever seen and unquestionably the best Simspsons episode ever.
It's the only film I've ever seen where everyone in the theatre was laughing at every single joke.
And those jokes are pretty much all dead-on perfect. In particular, the jabs at Fox, moviegoers and other movies are amongst the greatest jokes of their kind ever committed to 2D animation...Or indeed, live action. Sorry Epic Movie, your brand of cheap parody doesn't cut it against this film.
I'm going to be interested to see how this film does at the Box Office. I've seen some people underestimating its potential income. I think it's a dead cert blockbuster, but that depends on whether or not people stupidly decide to watch Transformers or Harry Potter 5 instead (Both of which could have been better).
And remember: stay through the whole credits sequence.
