Xhonzi, I'm not sure I get it. Did you or didn't you like the film? ;)
I admit I had a few similar gripes, though not to the extent that you did, and still I overall loved it. You forgot to mention that we Batman had about 90 seconds to get 6+ miles away from Gotham with the bomb, meanwhile escaping via some unexplained method and get another 6+ miles away in order to avoid being taken out in the explosion. (IIRC, the explosion had a six mile radius).
Perhaps I'll try to do a point by point and explain away what I can. But clearly there are issues of realism that both this and the second movie suffered from. Before this even came out, I attributed such changes to the inclusion of Jonathan Nolan instead of David Goyer as a writer. I think Goyer kept things a bit more grounded, though Nolan the Younger gets things more intense.
