Shall we start with the good things? Very good! The film is a sight for sore eyes, especially for sci-fi fans and for those who like very visual films with high doses of special effects, CGI or extraordinarily detailed scenarios. Perhaps the best way to be fair is really to avoid this comparative exercise, which is seductive and almost impossible not to do. After seeing the film, I had the feeling that we were looking at a very solid work that only lost when compared to the original franchise. The ship receives a mysterious signal from a planet that, by all indications, has excellent conditions for life, but quickly realizes that it has stumbled on a place where it should never have landed. The script accompanies the 'Covenant', a colony ship filled with people in hypersleep.
This film establishes a clearer, more palpable link between that film and the 'Alien' franchise.
I liked 'Prometheus', a film better than expected, albeit with a confusing script.
I don't know if I'm the only person to say this, but I think a horror movie works better if we see some intelligence in the script and in the characters' attitudes, and if the main antagonist is mysterious and able to surprise us.
