Where to start? Early on it had potential. That was quickly squandered by the really terrible CGI and numerous plot holes. If the virus killed off so many people, why are there so many still around? Apparently, you can't go anywhere without running into someone. There's a market and a train station. Why is there even a train if most off the population is dead? There is a nice neighborhood with electricity and parties. Why is the clinic searching for a vaccine in a dirty abandoned diner? The rebel faction fighting for animal rights has a poorly rendered CGI tiger chained up in a dark shipping container. Sweet tooth's poor father squandered 9 years of his life teaching survival tactics to a kid that learned absolutely nothing. And Bobby...oh my Lord...my wife and I noped right out as soon as he appeared. Why insert a cutesy puppet into the story if not for the Awwwww's? He made Ewoks look downright menacing. There is just no internal consistency. All of the rules are flexible when the plot needs to move in a certain direction. I can't suspend disbelief that far. It's just really bad. I can't imagine why so many people love it. To each his own, I guess.
