Too short, yeah, but good. Worth a rent, you'll finish in a whole-day game session.
Done with the pros, it has cons as well. Namely, it's short. Way less than 10 hours. Story telling is a little rushed. It could have told more. I expected to see character evolve around references to first episode. A few things to say probably made this shooter "short". Enemies also feel flat.
Finally, it's weird to hear people speak during action, with no lip sync...
My advice is: rent it, you'll like it, but don't buy, unless you find a great bargain on eBay and the like.
