Not bad up until the 3rd act

I was honestly enjoying this film decently (minus a few stupid moments) until the climax. It’s very rushed, confused, underwhelming and unimpressive. The big sendoff that kills all the zombies didn’t feel like that big final moment, more like something you’d see in the 2nd act action scene then the grand finale. I’m honestly not sure exactly what the character’s big plan was even supposed to be; they just go out there, blow something up, more zombies come. How was that even supposed to work? Did I miss something? Compared to the massive climax from the first movie, this one is almost nonexistent.

The first two acts were both very flawed but at least the plot made sense and the characters weren't unrealistic idiots. For whatever reason, that completely changes once the third act begins.
