I saw bad reviews before watching but still gave it a try
The 1st half of the movie is really strong. Good pacing, scary, it sucks you into the madness of that world.
The 2nd half however feels weak, the pacing is gone, the plot holes become easy to spot. The movie tries to be serious but then gives you a few absolutely cartoonish bad scenes. Basically it gets worse and worse.
Apocalypse Now has a structure where the first half of the movie is a total madness, probably one of the greatest movie experiences ever, then the 2nd half becomes much slower. But that movie is considered one of the greatest movies of all time obviously lol. This movie is nowhere near as good to afford this slow pacing towards the end. I felt bored and looking at the time when it's gonna end. And that ending....holly shyt it was bad, like really really bad. If I wanna watch a zombie comedy film I'd watch Shaun of the Dead.
