The game is decent. Takes about 12 hours for a full playthrough, more if you try to complete all of the "Sector challenges"
My biggest complaint about the game is the controls, especially when flying your Ikran (Banshee). The flying controls are just plain horrible.
The third-person view they chose is way off to the right of the character and it takes some getting used to, when you expect it to be more over the shoulder. Once you get used to it, though, it plays pretty well.
I found the ranged combat to improve 1000% when I turned ON the auto-aiming. Made the game feel more like the movie, as I could then hit what I was aiming at. It did definitely make it more "easy-mode" though.
The visuals in the game are absolutely gorgeous. Especially the night scene in "Willow Grove" or whatever it's called.
Overall I'd give the game around a 6.5 The controls really bring it down and the fact that they totally deviated from the story of the movie, but overall a fun game.
