This movie has some gorgeous visuals. And the design of the various alien species was great.
The action was pretty good, but nothing particularly special.
The storyline was derivative and unimaginative. If you've seen Avatar or Dances with Wolves, you already know the story. Story-wise, it was pretty boring.
And none of the characters were likable, especially the main characters. I spent most of the movie waiting for someone to punch Valerian in the face. The
Na'vi Pearls were sympathetic, but incredibly boring.
All in all, not really worth the time.
