Just getting around to watch this now. So far, up to chapter two, it reminds me a LOT of David Lynch's 1984 Dune.
[edit] Chapter 3 - Flash Gordon by Dino De Laurentes.
[edit] Chapter 5 - Good shoot 'em up with lotsa SFX and noise. I love the crop circles. Nice touch.
[edit] Well, we watched it to the end. More mindless violence, chase scenes and various actors chewing the scenery. My favorite was the "droid" that was assigned to get Mila Kunis through the bureaucratic maze. He had the best part in this movie, IMNSHO, of course.
All in all, a pretty good action flick if you ignore the overly convoluted plot, silly acting and a plethora of inane characters. The flying lizard people were fun, though.
