LIGHT SPOILERS
Just a big "meh" for me, it was okay. I was hoping to like it a helluva lot more I can tell you. The 3d was good (on par with but not quite as good as Avatar in that regard). I think the pace was a tad slow at times and there was no BIG payoff for waiting around for something awesome to happen. The action & suspense was a little lacking. There were some really good moments and a few WTF moments, and scenes that garnered laughs that I'm not sure that was the intention. There weren't a ton a references to the Alien films but one very big one at the end that felt, to me, incredibly forced. It did have kind of an "Alien(s)" vibe as far as the atmosphere was concerned.
Although I enjoy the first two Aliens films when I stumble across them, I'm not a huge fan of the "sci-fi horror" genre. I was hoping this film would give me a reason to become a bigger fan and it didn't. I'm not sure what big fans will think of this one, because it's clear that despite it's loose connections and references to Alien(s), the intentions are a little different as a story... :twocents-mytwocents:
