Why this movie didn't work... let me count the ways...
SPOILERS of course!
1. The excuse that no one nearby will call the cops when they hear the gunshots because "they'll just think it's fireworks." Well, maybe, except there AREN'T ANY FIREWORKS GOING OFF! It's a freaking blizzard! And they certainly would have called someone after 5,000 rounds of bullets went off like it was the @#$%! Alamo.
2. When Ethan makes a run for the bus and there's a bad guy in it - A) when he runs outside he leaves the back door wide open, B) the bus door slamming on his wrist and knocking the gun away was sooo stupid and sooo Hollywood and C) they get into a fist fight??? So this bad guy is the ONLY ONE who isn't armed? His comrades are practically Navy Seals, they have so many weapons, and THIS GUY has NOTHING???
3. Nobody else has noticed that an entire precinct in the city has been completely cut off, with no communication, for an entire night??? HOURS with no communication and no one is checking it out?
4. When the girls make a run for it in the SUV and the guy jumps up from the back seat and shoots the driver - they SLAM into a pole at like 40 MPH. The guy in the back should have FLOWN THROUGH THE FREAKING WINDSHIELD! At the very lease, he's got broken ribs, broken nose, broken arm, etc., but instead he bounces out of the backseat like nothing happened. Ridiculous. The blonde chick at least had bruises on her face, but she too should have been royally messed up.
5. Basically the whole premise - there must be AT LEAST 20 bad guys, all decked out in full riot gear, weapons, night vision, with a HELICOPTER -- how in the world did they get a hold of all of that without anyone asking what they were up to? What, they just rolled up and flew off in a police helicopter, in a blizzard no less, and nobody asked them any questions?
6. More of the typical 1000 rounds get fired at a group of people only 15 feet away and NOBODY gets hit - not even a scratch - on multiple occasions.
7. We go the WHOLE MOVIE with these guys supposedly trapped inside the building, only to find out in the final 10 minutes that there JUST HAPPENS to be an underground tunnel leading outside? Are you KIDDING ME???
8. Letting Bishop out of his cell was faulty logic from the very beginning: What will the outcome be? Either they can turn him over at the beginning of the movie and no one dies, BUT HE GOES FREE, or they let him out and give him a gun and... HE STILL GOES FREE! What, is he just going to give you his gun back at the end and turn himself in?
9. Then Bishop staggers away, bullet in his gut, with Ethan Hawk telling him he'll track him down. Minutes later the cavalry arrives, police EVERYWHERE, and Hawk doesn't mention Bishop to ANYBODY! Minutes earlier he vows to find Bishop and now he can't even take a few seconds to tell the police there's a really bad guy wandering through the woods bleeding?
