That can't be happening!

Rating: 4/10 (20 September 2012)

When I was reading the reviews about this movie, I thought people were being overly critical due to their high expectations especially because of the high bar set by the previous Alien movies. However, I came to realize that people were actually being too generous on their evaluations.
I have seen every single Alien and Predator movie, including Alien 1-4, Predator 1-3, and AvP 1&2, all of which were decent movies with the sole exception of Alien vs Predator 2, which, although a bad movie, still manages to shine as a masterpiece compared to Prometheus.
I have absolutely nothing positive to say about this movie. It's a purely awful movie from start to the very end. Nothing in it makes sense, and there is not one scene which is worth re-watching. The movie is utter nonsense, regardless of where you are coming from. In short, it is one of the worst Sci-Fi movies I have seen in my life, and I am not even such a nerdy, overly critical fan. I am a regular dude who finds it ridiculous to be a Trekkie or Star wars fan etc. I just like Sci-Fi as it enriches my imagination and saturates my curiosity about technology and that's about it.
Given all that... These are my impressions about the movie in a nutshell...

The script is VERY superficial, with no depth, but enormous loopholes, and possibly hundreds of serious mistakes. It's basically no more than the imagination of a 7 year-old. AvP2 shines like a bright sun compared to this movie, and please do not even compare this piece of garbage to any of the other Alien or Predator movies, since you'll simply be insulting those decent movies.

The scenes all seem like random shots of completely unrelated peaces stitched together. You may as well watch the movie completely randomly, and won't be missing much. The whole plot lack any kind of fluency.

The characters have no real personalities (forget depth of character), many of them are nothing but "extras" waiting to die. There are probably 2-3 characters worth mentioning, you would be just fine without any of the others.

====Possible SPOILERS==== - The Alien characterization makes no sense. It's not even compatible with the any of the movies in the series (Alien needing to nest "2 separate hosts, and growing into gigantic proportions???) - The CGI effects are good but nothing spectacular. To me, they were underwhelming. I didn't go to movies for the effects but even those can't save it.

There is no suspense or shade of thrill in the movie. There is no part in the movie you see real science, or people acting as they should. This movie has lots of dumb characters (and scientists!) and how the hell those people were chosen in such multi-billion dollar project? How can a dumb person be a scientist in the first place? ====End of SPOILERS====

Oh my God, I can't take it anymore... This movie doesn't even deserve a complete review, and not worth my time, writing all this... This is the biggest insult to the Alien Series, and I can't believe it was even green-lit and shot. Didn't anyone read the damn script?
Long story short, this is a terrible movie for sci-fi fans or any other person alike, and the only good thing about it is the potential premise regarding the origin of the humans and aliens.
