I saw it a couple of nights ago.
Hmmmm... what can I say. The 3D was not that good.
Too much "over the top" action. Girls being "backhanded" by massive warriors, only to rise and fight some more.
OK storyline, not (too) bad acting..
I'd rate it about 6-7 out of 10.
I honestly expected better.
But that's just me. You may love it.
These things are always subjective. :)
