Disagree about the acting... a lot of it was really bad. I liked Cranston, and I guess Ford + his wife were fine, but Ken Wantanabe as the scientist/doctor and most of the military folks around him were abysmal. There was one part where I physically cringed because the delivery was so bad. The thing is I know he's a good actor, I've seen it. It almost seemed like he was over-acting on purpose to get the old B-monster-movie vibe, but nobody else got the memo so he just seemed really out of place. I just don't understand what he was doing, and why nobody else acted the same way.
This, very much this. A lot of fluff and bullshit that wasn't well acted enough to spend that much time with it. The monster encounters were all pretty badass though, so it was worth seeing in the theaters once. Probably won't see it again though.
