This was a pretty good movie. There was lots of action and a good enough amount of guy stuff (explosions and special effects) as well as gal stuff (romance).
Beware, it does make us Terrans look bad by portraying us (mainly, the military) as profiteers who are careless about nature and human(oid) life ... especially since in this movie we destroyed our planet and are trying to destroy theirs.
Being retired military, I take a huge issue with that. Since I now work for a contractor that does substantial environmental work on military installations, I can tell you that federal government agencies (including DoD) are committed to maintaining a healthy balance between the environment and necessary progress.
