The jury's out for me. There's no way that the film can be judged based on this trailer alone. The music all but guarantees that because it shapes the mood of what we're seeing, even though it's just temp trailer music. I'm withholding judgement.
That said, me being pretty much spoiler-free, it sure does kind of look like a note-for-note remake of ALIEN, doesn't it? But come on, it couldn't have taken them three years to write an ALIEN remake. I hope that there are many surprises left out of this trailer.
[p.s: Is it just me, or does the captain have a bit of a Tom Skerritt vibe?]
