This is a strange movie. It seems like it'll be a comedy, but it's actually a drama with one or two jokes thrown in. It seems like it'll be a short-and-sweet type of thing, but it's actually very long and very drawn out, with two entirely different sections of the story (before and after he learns that he's not going to die). And most of all, it seems like it'll be pretty entertaining like Judd Apatow's previous films, but it's actually horribly dull.
The performances are pretty decent, but at no point does this film feel even remotely pertinent or meaningful. It's just about following Adam Sandler around as he goes through a series of mostly mundane things. There is never really any point, and any attempt at being poignant and emotional fails quietly.
Still, it's not a bad film; I can kind of see what the director was going for initially... it's just that whatever that was, he didn't succeed, and ended up with this instead.
In a sentence:
Ridiculously drawn out, dull and uninteresting, but with some decent performances and otherwise good writing.
