Little thought about this movie. Without spoilers:
I did not hate this movie, I think it was an okay prequel that tried to respect the original. But it should have been better, IMO.
This is a prequel AND a kind of a remake so it have all the problems that remakes have and all the ones prequels have.
We already know, more or less, what will happen because it's a prequel AND they also use some scenes that echoes the original one,
so we are not very surprised by the way it happens.
Now I guess it's okay from a story point of view: human characters reacting a bit the same in both movies is understandable
because the situation is the same. But that can't make the movie very interesting.
Th CGI are also not amazing. They are not terrible, but not good enough to make me feel the characters are in real danger.
I suppose this is also due to the direction of the movie.
Too little time presenting characters leads the audience to not bothering who is the Thing, who will die next, etc..
(I like Mary Elizabeth "Sygourney" Winstead and Joel "Kurt" Edgerton in this movie though).
Last but not least, the other thing that bothers me is that if someone watch this movie first, he propably likes it more. But then the amazing original will seems like a rehash to him. And that is a bit of a cinematic crime.
Now, it's a not a BAD movie. It was interesting to watch. They did a god job doing what they were supposed to do.
If you like the original JC's movie you should see this one to make your own mind about it.
But...
bottom line is: I was not scared a single time while watching it, and that means fail to me.
