Not as good as I thought it would be. I would rate it after the fourth movie in wtfness. Characters were too contrived, the makeup on Guy Pierce was just awful (the dog stole the first scene he was in), the music was in your face, surprises were telegraphed too in advance, plot made not too much sense (too me). I did miss the first few minutes - Orange Wednesday is a bitch, queues were longer than I expected and that was just to pick up tickets paid for in advance /grumble - so I don't know if anything important happened when that albino guy keeled over into some water, was that important? I also thought I'd walked into the wrong movie screen as I thought that was Voldemort at first and I was trying to comprehend what was going on.
So the film, sequel or no? I would hope that if they did, it has no connection to the original Alien movies as I don't want to tarnish their memory.
