Reasonable sci-fi romp with a dash of confusion. SPOILERS!

Rating: 7/10 (5 October 2012)

First of all, if you haven't seen this I recommend you do. This is a little different to most science fiction movies I've seen. This is not a genre I particularly like, so for me to give a seven may mean fans of the genre will love it.
If special effects are your thing, you won't go wrong here. Again, for me a movie needs a decent plot to work and not just effects. So, does Prometheus cut the mustard? Well...only just. The plot is very hard to follow but the good(?) news is that there will be two sequels which may explain a few things.
The scene at the beginning with the big baldy alien drinking the stuff and dying in the water really confused me. I thought of two reasons. One, the protagonist flew to the alien's planet and somehow poisoned him (she said she was going to the alien's home planet next) or two he was killed by his own people for some reason.
I am ashamed to admit I looked up some explanations for this after the movie. That for me, is a bad sign. You don't want your audience confused. Worst thing is you get assholes saying 'Well, if you have a very high IQ you'll love this movie and totally understand every minute of it.'
No you didn't. Now shut up.
The alien's hatred for us is confusing, but may be explained later on. The DNA match and the effect drinking a drop of blood had was a big leap of faith. The bizarre and disappointing scene with the old man looking for the meaning of life and getting his head caved in was another let down.
The final scene with the birth of 'alien' must have been a massive let down for fans of the first two movies (Alien 3 and all that Predator nonsense are not worth including). For me, that smacked of ''we marketed this as an 'alien' movie...we gotta give them something.''
Despite this, there is still enough in the movie to like. I just hope the makers explain a few things in the sequel.
And it would be most funny if the makers proved the 'beard scratchers' wrong on their 'obvious answers'.
