I went and saw this this afternoon (yeah - seems weird to go to a movie in the afternoon!). It's quite a big let down. Sure, it's got lots of effects and style but substance is missing. Much of it is just a 3rd rate Hollywood lets-fight-the-bad-guys-with-big-guns type of movie with shlock dialogue glorifying human foibles. What a waste!
The first movie was excellent with ground-breaking cinematography and innovative adaption of the wire-flying martial art film techniques. I also thought it was pretty brave using such a hardcore sci-fi plot in a mainstream movie. The whole issue of reality could have been such a rich plot device.
No, it's just a stylish war movie with an incoherent cosmology and an uninteresting script.
