Yep- I think it's a great movie. anything was going to suffer in comparison to the first two which are basically perfect.
apart from a couple of dodgy effects shots, it still looks gorgeous in my opinion. love the setting of Fury 161 which has it's own feel.
also love how nihilistic it is for a Hollywood blockbuster. kill off the happy family from the last film? bunch of rapists and criminals at the dead end of the universe? no happy endings for anyone? wow.
the only entry in the entire saga which got anywhere close to the isolation and claustrophobia of the first film.
it was also the first Alien movie I was aware of, when it was actually being released. I was still too young to go and see it at the cinema, but I remember the hype, the video games and merch being released etc. I've got the Dark Horse movie specials here which I found in a comic store.
could it have been better? sure. I realise that it was a mess to make, and even many of its strengths came by accident rather than by design.
I've also often thought that it doesn't even really know what genre it is. is it a horror film? not really. is it sci fi? kind of. but again not really (apart from the beast, is there anything here really integral to the story which comes from sci fi?)
it's not even really a prison drama haha.
