Overall, a pretty great movie with some glaring faults. First, the good: the last fourty minutes or so are a bloodbath that will not be soon forgotten. Also, acting was spot on with Fassbender making a wonderful cyborg. But, that being said, Alien: Covenant took way too long to get started, and the first two acts dragged on way too long with unnecessary extra story. My only other complaint is that Ridley got a little too crazy with the obvious CGI.
Overall, a great movie but maybe wait for the cheap seats or blu-ray release.
