saw this at a free advance screening tonight, full imax 3d so good screen and audio. No spoilers, but I wasn't that impressed. The monsters were awesome but unfortunately they have about 10 minutes of screen time, almost all at the end. Most of the movie is pointless human shit, done by shitty actors. Would rate this at 6/10, with Pacific Rim going at 7/10. All the things that were cool in PacRim are here, all the things that sucked in PacRim are unfortunately here too.
Would not recommend it as a theater movie, nothing so spectacular that its worth the ass raping theaters give now. Will be an ok home theater flick.
There really isn't any Origins story or interesting mythology here unfortunately, felt like it got heavily dumbed down to play for International audiences.
