MattWillPost’s review published on Letterboxd :
Dude, this is the best zombie film I’ve ever seen.
While it has a pitchy premise (zombie apocalypse but you’re on a train) it’s actually way more than that.
Wasn’t prepared to feel what I did when I started watching this genre film. I felt hype, despair, fear, & I think the most important word is: Invested.
I use to have an obsession with zombies movies when I was a kid and I don’t think I was THIS invested in one since.
