I liked that this film looks like you're playing an FPS with zombies. I didn't like all the rest.
Stay away from this.
I see this as a lesser serious version of John Wick, that struggles to find its own identity, but manages to be something different from it. I loved the action scenes, they are really raw and brutal, I wouldn't have expected such violence. The rest of the film doesn't take itself too seriously, and I think that was the best tone it could have. Special mention to Christopher Lloyd, probably the funniest part of this film.
There's so much to tell about this movie that I don't know where to begin with.
I've seen a lot of revenge stories and most of them are not this good, because this finds a way to turn a classic plot into an original one. I loved how the film is always evolving, and offers you something of always different from what you've seen before. Maybe the ending is a bit too exaggerated, but the growing climax throughout the film…
