The supermarket scene seemed rather silly. I know shit is going down out in the world, but I find it hard to believe that even in craziness, people would just sit there while a women is obviously screaming for help and being held down by two men, and just let it be.
And what was the deal with Thomas and family? Why even have the family in there at all? To counteract the whole "people let rape happen" scene? Next, when Brad Pitt tells them "I worked in dangerous places, people who moved survived, people who stayed died", why the hell didn't he tell them about the helicopter? Of course they didn't go with him, for all they know, he's some guy running to the top of the building. Why not just say, "Hey, there's a helicopter coming, let's get the fuck outta here".
The scientist guy pissed me off too. How the hell do you manage to shoot yourself like that? I get it, a metal plankway is slippery, but it just seems impossible when falling to have a gun in your hand shoot you in the head. Unless it was a ricochet or something?
As far as the South Korea landing, what I got was, it's the Doctor, Brad Pitt, the Pilot, and one (two?) SEALs. They land, the Zombies start moving, and the Doctor kills himself. Maybe another SEAL dies, or maybe that was one of the base soldiers, but three people go into the base. And when they're leaving, it's Pitt, Pilot, and SEAL on the bikes, with the Base Captain driving the fuel truck.
I'll throw in a little defense for the wife, she didn't know what Pitt was doing, and he had just tried to call her. When people try to call me, and our call is dropped or something, I know I call them back, so I think she's excused. As for Brad Pitt.....turn that shit on vibrate man! Anyways back to the base, because the phone goes off, the fuel truck has to come early before the 3 of them are holed up on the plane, so they fight their way on the plane while the Base Commander starts the fueling process. But he's forced away from the truck, and apparently the plane can't take off without the pump out of the plane, so that's where the SEAL guy leaves to go take care of that while Pitt/Pilot lock themselves in the cockpit. The Base Commander gets bitten and commits suicide, and the SEAL guy is probably just eaten off-screen
The City thing really pissed me off. So there's an entire city behind the wall, filled with cars/buses/millions of people/and a security checkpoint, but maybe a couple hundred people singing a song over a megaphone is suddenly "too loud"? Bullshit. And you're telling me that don't have guards up on the wall? Or a helicopter circling the perimeter of the city? To make sure that sort of thing doesn't happen?
And the Israeli girl was one of his escorts in the city, and I guess they just decided to stick together after escaping Jerusalem.
As far as the WHO facility, it just seems odd to me that such a state of the art facility would have so many squeaky hinges, maintenance has really been slacking.
My last gripe with the movie, is when he's picking which deadly sickness to use. There's almost a bit of tension since if he picks a too potent one, the assumption is he could die before making it out. One of the Doctors even says "No, don't pick that one." and "If he uses any of the ones from that left cabinet, he's dead anyways". So why doesn't he hold up a sign saying "I'm going to hold these up to the security camera for 10 seconds, you call the phone and let it ring X times with the one that will let me live longest" or something like that. But then he's given a magic shot and there's no worry.
All in all, it was a pretty enjoyable movie, better than Man of Steel anyways, even if the characters did suffer from Horror Movie stupidity.
