Seriously... my 4 stars are 2 for acting, 2 for special effects.

Dialog get's more or less 0, because it sounds like it was hashed out in about 10 minutes.

I'd normally save the rest for plot, but there was none... If you watch the trailer, and I tell you that she survives.. you would then be able to convince anybody else who's seen it that you'd seen it too.. I'm sure plenty of people will say that's an exaggeration but I promise it's not..

If you meet anybody who says it's good, try this out for yourself and see if it works!

The special effects are amazing, but it's like the icing on a missing cake - you have to have substance first. Bear in mind I'm a huge fan of movies like inception and the matrix, movies which some would accuse of being more special effects than plot - but this takes the biscuit.

I'll say no more, because the trailer plus the inevitable ending speaks for itself.
