Criminally underrated
Sure, some aspect could have been done better, but this had some real gems. The social commentary was spot on in some points (A Corman version of Idiocracy, for sure), and some of the effects were surprisingly good. I also enjoyed the music (not the "Drive kill" obvious nonsense, but the soundtrack was great)
Bottom line, I enjoyed it. It was over-the-top and imperfect. If you want a bland movie with a billion dollar budget, this isn't for you. I've seen Michael Bay movies that were less enjoyable and made less sense than this movie.
