Wow, unexpectdly cool! Apart from the last scene (wtf is the giant cube? Where's gravity? Shouldn't the force be centrifugal when rotating?) it was good, visually pleasant considering the awful poster and the (I guess) not-so-great budget.
Starts really good, but towards the end it's just getting absurd. Could have been a really cool movie!
This starts as an amazing movie but then with the third act it gets a little bit off the rails.
Overall it's a good movie, with an excellent soundtrack. And the cinematography is great, so don't judge it by its (terrible) poster.
