your talking about how realistic it is to kill a huge monster...doesn't really work.

And most of those that didn't like the movie didn't like it because it didn't explain everything. Well guess what, that's the perspective of the movie, you know that going in. If you were living in NYC when that happened, YOU wouldn't know what was happening or all the lose ends, that's the WHOLE POINT. It's fine if you don't like the movie, but let other people find out for themselves, some people enjoyed it quite a bit, like me.
