Actually, that was a decision made purposely. J.J. Abrams also is the same guy who does Lost. There are alot of online offical websites that help explain some things, also alot of the viral marketing includes hints and about 4 or five different theories on what it was.
Also, how likely is it that those kids would have any clue what was going on?
I think if you are over the age of 32, you prolly won’t like it. If you are under that age, this is an event movie.
The one thing I know for sure is this movie will have about 3 sequels if not more. The amount of money it has made and the open plot lines of the Pentagon finding the tape, how they did, is the creature still alive, what is it supposed to be, does it move onto any other cities now etc....how well do nuclear weapons work towards aliens blah blah blah.
Funny, we did the same... my stepson recommended we sit in the back for that very reason. When we got to the movie theater (early) a big cluster of people were already sitting in the back. One guy sat up near the front during the entire move. I wonder how he felt when it was over... LOL
I wouldn't have gone to see this movie, except my stepson wanted to see it. It was somewhat imaginative, I suppose, but I think I'd also give it a "C" grade overall.
