I watched Prometheus tonight and enjoyed it. I was expecting something a bit more deeper when I would be scratching my head afterwards trying to work out exactly what was going on. It was however quite straight forward, a prequel to Alien with all the usual Alien ingredients with only one question for me concerning the cave paintings.
I googled it and wished I hadn't as every nerd on the planet (as well as me ) had an opinion on the paintings not to mention every other aspect of the film
