Ah, it's a fairly funny movie, but it's rather predictable! It has a good number of moments that can generate some decent chuckles but other than that it's more of a funny idea than a funny movie!
I guess they were trying to appeal to kids more than anybody, which would explain why the humor is so obvious throughout the movie!
I thought it was pretty funny. Who cares if it's predictable, at least it's not completely fake like those action movies for kids (SpyKids, Catch that Kid, etc.) I like the part with the fat guy and the pinata joke XD
I watched it with my GF and we laughed a lot. It's stupid but who cares? Everything doesn't need to be 4 stars to appreciate it. Last night I watched Fast Five and it was awesome with a couple good looking babes in it. Google Elsa Pataky and you'll understand what I mean by good looking babe. :O
...funny, but in my opinion, it's funny in the same way that you can make fun of a semi-mediocre movie. I remember the movie rather well, but it isn't because it was a memorable movie. it was somewhat original, but the concept was ruined when an R-rated version of that movie (observe and report is what I think it was called) came out roughly the same time.
The whole "fat" thing got old halfway through the movie. I much preferred Observe & Report, even though it was the same basic idea and it was released a few months after Blart.
