Oh sure, it was hysterical. I'm tempted to offer specific examples of why it was so funny, but then I'd be belying the point of this posting.
In today's new media world, it's very likely that you'll be able to see an entire movie without ever going to the theater. It won't stop you from going, particularly when a film is good, but it could compromise your enjoyment somewhat. Almost all of the funniest scenes in the film could be anticipated based on videos I saw or very specific reviews I read. Is so much prior knowledge really good for a film?
I still recommend you see it, but do yourself a favor: Don't shout out the lines before Sacha Cohen does or you might spend the next few hours removing tiny kernels of buttered popcorn out of your clothes and hair (or maybe that’s just how the partons of the particular cineplex I went to show their appreciation).
