Not a single likable character

Rating: 4/10 (21 October 2012)

I was really looking forward to watching this movie as I am a huge fan of Alien, with its dark, brooding horror and I had no idea of the storyline of this film.
As I started watching, I was waiting for the appearance of a character that I could relate to. Then the movie finished and the credits came up and I still hadn't found one (I thought the captain was almost likable but you didn't see much of him).
It's now some months since I saw the film at the cinema and I bought it on Blu-Ray thinking that my kids might enjoy it (I have the Alien Quadrilogy so had to buy it to complete the set so far).
I sat down to watch it and was even more disappointed in the weak characters the second time around.
What a sickening bunch of corny, one-dimensional prating buffoons! I established absolutely no empathy with any of them, so it's therefore not possible to care in the slightest what happens to them.
Has Ridley Scott lost it?
More importantly, why does IMDb auto-correct my heading and change "likeable" to "likable"?
