Same here Lisey...
I went again last night cus my group of friends from back home was going. The second time around it became far more clear to me that it was Frank from outside the movie store, and that it was the same night seeker who saw Robert with the first trap, released the dogs and then later appeared in his basement. I think those bastards lured him!
Two more confusions though.... It's pretty shaky how the night seekers would know where Frank was, and if he would even attract Robert. They almost certainly would know nothing of Robert's usual habits such as saying hello to Frank and where he was, as they cannot move from building to building watching him right?
AND
How the shit did Anna and Ethan get onto Manhattan island? The tunnels were flooded, and traffic jammed, and probably infested with night seekers. Bridges were gone. And yet she showed up with not just any SUV, but a decked out one with UV lights already on it, meaning she didn't just hop a boat and steal a car. And again at the end, she showed up at the survivor camp in the same truck, meaning she must have parked it a ways away from Robert's house (or it would have been blown the hell up) and then carried/dragged an unconscious and injured 170lb man onto the couch
Dont get me wrong, I loved it. But these two questions, combined with what I thought was a very rushed ending (oh look, the cure...here hide(in this coal chute wont heat to 450 degrees when a hand grenade blows up and then cooks my lab)) made it a little disappointing, when I'd been re-watching other post-apocalyptic science ficiton movies in anticipation of this one for months
....I'm still guna buy it
