I think the real issue is that for some, the sole interest in this was hope it would have direct connections to ALIEN. Meaning the same planet and the actual xenomorphs.
I am not in that group. I am a casual fan of the original at most. The idea of a film being in the same universe but with different characters and no real plot connections is interesting.
For me the real question, is this a movie that works on its own terms? Will it appeal to me personally and do I have a strong desire to even see it in the theater. I am not sure of that yet. I would have to hear its a must see for anyone. Beyond fanish hype.
