the second half is a fun and absorbing ride and I came out feeling satisfied. Pity the first half was basically pointless. The flimsy story is shot as an epic but epic it is decidedly not. The sci-fi aspects fall flat and the characters and situations are pure cliche. This movie didn't need to be 2 hours long, 90 mins would have easily sufficed and actually improved it by removing some of the pointless fluff in there.
