I didnt like it at all. There was no plot. There was almost no script. There were numerous suspension of disbelief, eyerolling moments.
It was like they took the last 20 minutes of a film and stretched it out to feature length.
It looked to me like some suit said, "We can charge more for 3D movies, make me a 3D movie", so someone did it, pasting in some floating doodads in post production
I actually was thinking halfway through that the film was rather boring. It was just visuals and nothing else.
