Whats more to expect When we say Action | Adventure | Sci-Fi the storyline is mostly pre-set. But all we want to see is good imagination coming out via a nice and entertaining media. This packs them all.
You got Action, yah lots of them. You got si-fi, definitely and it's a action packed adventure. And there's no more to say. You'll love it just as I did and the story surely is promising!
One more thing, the design of the aliens are great cause there's no artificial nature associated with them as a life form. And graphics are superb and it's not a surprise cause this is developed by the studio which did Transformers!
