Yeah... it was much much better than Alien 3. I actually still have trouble accepting Alien 3 as an official Alien movie because they killed a huge part of what made Aliens so good. James Cameron has been known to hate it. He felt killing off Newt and Hicks was a huge slap in the face to Aliens fans... and I agree. To me, the Alien series ended after Aliens. It's not the first Cameron series to make me feel that way, either. The Terminator series ended after 2 in my head.
Anyway, onto Prometheus. I actually think Scott did a great job of revealing enough to keep Alien fans enticed but keeping enough hidden to keep interest in sequels. A few things I'm glad he answered...
and some theories of my own...
So overall, I was very happy with the new life and possibilities breathed into a dying franchise. The pacing in the last half of the movie was choppy to say the least, but all in all I liked it a lot. I can't wait for the sequels. This is something new, too, because with each AVP movie that came out I cringed more and more and just wished they would stop.
