That's been one of my favourite movies since it first came out (I was 14 or 15; so just about old enough to blag my way into our kinda-lax-on-their-underage-policy local cinema at the time). Superbly written, filmed and acted, and Kevin Spacey... just,
wow. He's on screen for all of about five minutes and he completely stands out as one of the greatest movie villains of all time.
For marks out of ten, I want to give it a ten just because it's always been such a personal treasure to me. But I haven't seen it in quite a few years, so nostalgia might be misting me up a bit, and nothing's
really perfect anyway, so I'll back off a little and say 9/10.
Prometheus?
