"Collapse" wasn't as bad as I had initially expected it to be.
For a zombie movie, "Collapse" was a bit out of the ordinary. Sure, you had the unexplained phenomena of people returning as zombies hungry for human flesh, as in most other zombie movies, but it was also a story of one man's spiraling journey into madness.
The zombies in the movie were not too badly made. The make-up was adequate. Though one thing did puzzle me, why did every single zombie have to be wearing torn pants? Is shredded pants a requirement for being a zombie? The zombie eyes could have been made better, have them wear contact lenses. When you see a zombie with ordinary eyes and even see them blinking, the whole undead menace thing falls shattering to the ground.
And there was one scene where Morgan was shooting zombies in an office, and one zombie was shot in the head. The zombie adjacent to the shot zombie flinched and squinted her eyes as you would do when something is approaching your face. That kind of error is just fatal in a zombie movie, as it was painstakingly obvious that these were not reanimated corpses.
The story did take a twist for the unexpected in the movie. I hadn't seen that coming at all, so it was a nice twist. Now, whether or not you approve of how the story took a turn with that twist is individual, for me it was a turn for a downward hill. I didn't like that direction of the movie. It was a great plot twist, sure, but I personally think it was just not plausible. I am not going to ruin the story for anyone, as I think you should see the plot twist for yourself and make up your own impression of how the story took a twist of events.
Being a zombie aficionado, I can not cross "Collapse" off the list. It didn't leave a lasting impression really, as it was neither good nor bad.
