Prometheus is certainly sepectacular to watch but I don't know whether it's because I've not seen any of the Alien films (nothing to do with not wanting to) and am not wedded to the concept but I thought it was very good, not great.
It has a fantastic cast with some superb performances - particularly enjoyed Michael Fassbender as the sinister robot Michael - but the script feels at times a little clunky and action movie 101. I felt talked down to as if I wasn't quite bright enough to keep up with not very complicated plot.
My other bug bear is that for a group of seemingly highly intelligent human beings they aren't half stooopid. I suppose they have to be to generate the narrative.
It is a visual and effects feast though and I'd love to see all the 'makings of' stuff but it somehow lacked a bit of heart. You never really get under the skin of Noomi Rapace's character in order to fully understand her motives or to empathise.
So much to be admired but not quite satisfying to be a rounded hit, I am giving it 78%. On IMDb it's got 83% with a Metascore of 63%. While on Rotten Tomatoes it has 80% from critics and 87% of site visitors have given it three and a half stars or higher.
PS I spent the whole film thinking that it was Tom Hardy was playing Charlie Holloway when it is in fact Logan Marshall-Green - those two could be brothers.
