Although this is not a great movie, I was positively surprised, given the tons of bad references I got from this movie.
The background story is interesting and the cast is quite decent. Theron and Elba played well but specially remarkable are Rapace and Fassbender.
In any case, it does have many flaws in the script. Several characters are stupid beyond comprehension, several things are completely unexplained, Pearce character is really bad and the crashing of the alien spaceship is just ridiculous, as it is the killing of Theron's character.
In any case, it doesn't leave a bad after taste and I am looking forward to the continuation of the story.
