Was so disappointing I though it could have been so much better and with the leaking of the original draft (Alien: Engineers) it turns out that it originally would have been. The script was heavily modified by a different writer and that kind of explains the modification (rather than re-write) caused so many plot holes.. would have been great if they did it right.
