Caporegime
Entrapment. Pretty stupid story wise, and the acting wasn't up to much, particularly from Catherine Zeta-Jones. Some of the action sequences were great, though, and even if her acting was awful CZJ is pretty stunning.
Prometheus - Not a fantastic film by any standards, but it made me want to watch the second.
I think a 6/10 is sufficient.
There was absolutely no need to add the Alien to this film. It could have worked as a standalone trilogy with a bit more thought to the plot and characters.
