It was entertaining...
...but it bothered me how inconsistent the behavior of the characters was.
One minute they're pretty smart and the next they do the most boneheaded decisions possible.
For example, the characters are smart enough to realize that the zombies won't attack them if they don't see them so they'll put the newspapers on the doors, but the next minute they'll forget to close the door or something similar like that.
Btw., did I miss anything or was there an explanation how the main character realized that the zombies won't attack them if they don't see them? Seriously, how did he realize that? I can't remember.
Why didn't they do that with all the doors? They had enough material.
The only reason why that girl was bitten in the end was because they forgot to close the door, you'd think that would be their priority.
Also, a pretty stupid part where the survivors who chased away the others effectively trapped themselves among the zombies.
There's no excuse for that. You can say that they were afraid, but hey, their other decisions were motivated by fear as well and they managed to survive and think logically. Why they didn't move in a different cart and then tied the ropes to the door, I have no idea.
I'm pretty sure there were some other examples.
My point is, you can have tense scenarios without turning the characters into "zombies". There were many well done scenes like that, like the scene where they use a phone to distract the zombies. Why not have more scenes like that? You can have the tension, the conflict etc. with smart characters too.
Is it just me or was the zombie behavior really inconsistent as well. In the scene where they're going through the tunnel the characters realize that zombies will ignore them in the darkness because they stopped attacking them. Zombies couldn't see them so they stopped attacking and relied on sound.
But, in some other scenes when the characters were in the darkness, the zombies didn't stop attacking, they continued to attack. Sure, you might say "that's because the people were making noise", but hey, the characters who realized that the zombies won't attack them in the dark were also making noises when they realized the weakness.
Like some other people said, the time it took for a person to turn into a zombie seemed inconsistent as well. Some people said that it takes more time when you're bitten in the arm and less when you're bitten in the leg.
But remember, the girl who went into the train and started the infection got bitten in the leg as well and didn't turn nearly as quickly as the girl at the end.
I think the reason for that, and other examples above, is: "The script asked for it."
The characterization was also lacking in places. Apart from the father, daughter and that guy with the pregnant wife (and maybe the guy with the baseball bat and the girl he likes, I forgot their names, sorry), other characters weren't so good. Sure, that's understandable when you have such a big cast, but the villain was pretty lame (why did the movie even need a villain) and you'd expect that the characters who lasted longer would get more character development.
What about that traumatized guy in greenish clothes? He lasted almost till the end and was just freaking out almost all the time until he decided to sacrifice himself. That's basically his whole character.
I'm also confused by the people who say "It doesn't have much cliches". Umm, yes, yes it does. It had a lot of cliches.
The main character was a cliched one, but was at least well done.
There was also that cliche of kids not dying (though, I guess that was expected).
The cliche of the hero dying.
The bad guy was a typcial jerk who only thinks of himself, you can find that in almost every zombie movie.
The characters splitting up.
The characters arguing.
etc.
It had a lot of them. It really didn't have much original ideas, I wouldn't even call the setting orignal, I'm pretty sure we have a movie called "Zombies on a Train".
But don't get me wrong, it's an enjoyable movie, it has some nice characterization, some nice drama moments, some nice tense scenes.
It's definitely overhyped though(I get it that people have different opinions etc., but is this really the best serious zombie movie in some people's eyes? What about Nigt of the Living Dead? Original Dawn of the Dead? etc.), but that's to be expected from asian movies here, if this movie wasn't asian one, it wouldn't have such a high rating here.
Hell, it even has some of the same things people complained about in World War Z, like the main character figuring out how zombies work instantly and zombies making silly faces.
It's not scary, but I don't mind it, I don't get scared by horror movies anymore, plus this had a lot of unintentionally funny moments.
