Great watch, would watch again, and can recommend.
Probably the worst part of this is a trend I'm noticing from some movies I've been seeing recently where they show you what could be a better movie, in the movie.
While this starts with a "patient zero" style opening, they then skip past the movie I want to see to the last possible story from the opening event.
This movie does do a lot though, and has a lot of moving parts at any given time.
Batista is amazing, and everyone sort of gets lost around him, I can't tell if that's because he's a giant or if the movie wants it that way: the cast all does a fantastic job in their roles.
The movie does a couple things that I don't typically enjoy in movies: smart zombies, obvious traitors, and secret motivations. It's like if SHIELD was in "I am Legend" and Black Widow kept tripping everyone else to get a rare Pokemon card.
That said, they show a fantastic amount of detail and complexity to a society that is barely explored, adding a wonderful flavor to the story.
