Mostly just a big CGI mess. During the actions scenes that took up about half the movie, it was impossible to tell what was going on, but I didn't really care. The rest of the movie was either very dull, when characters were standing around moralizing about whether it was OK to harvest people for their own benefit, or a little bit creepy and a lot silly. The ease with which Jupiter accepted the fast-moving string of worlds and disasters and murder attempts and aliens and kidnappings, while falling in love with an alien half-wolf, half-man was, except in the most ridiculous of comic book worlds ... Oh, wait.
