I wouldn't say I buy into the hype with weapons either, this is pretty close to being all 10 movies that I liked this year so ranking it at #7 isn't saying a ton. having seen both barbarian and weapons now, I feel like cregger's "shtick" is to take a pretty basic story and make it seem more complicated and mysterious by structuring it unusually.
I wouldn't say I love 28 years later because of the stylistic experimentation, if anything some of the nonsense like the camera spazzing out during action scenes took me out of the film a bit. but I love the tonal contrast of it, it's able to be this somber, reflective film about dealing with terminal illness in the immediate family and also this unhinged action thriller with big dick zombies that rip out people's spines. loved the characters too, would watch a whole-ass movie about ralph fiennes' zombie apocalypse john locke. I've seen a bunch of reviewers comment they loved the first half but didn't like the second and vice versa, and half of everyone saying they hated the ending. I think that all speaks to the diversity of it and personally I loved it all, first half, second half and ending. it's just a cinematic buffet of a movie that gave me at least three movies' worth of movie in less than 2 hours.
it's also a pretty thoughtfully written movie with a bunch going on beneath the surface. liked this video analysis despite the clickbaity title
