What I don't understand, above all else, is why people who are clearly not part of the demographic that the movie is aimed at, criticize it as if it was and then seem happy for the failure of a movie not directed at them.
In a way, it's kinda like the 40 year old dudes who complain about Twilight and don't understand why anyone would see it.
The demographic the movie was aimed towards is too young to decide "I hate 3D I hope this fails". They were old enough to decide, however, "This doesn't look interesting, mom and dad, please don't take me to see this". And, frankly, mom and dad were fine with that decision.
