For me...
Alien ( 1979) is the top...
When Aliens came out, I liked it..till I saw the first aliens... how simple they where killed..The whole magic and mystery was gone...and That Alien Queen thing..turned the Alien in insect like creatures..so pitty...
I don't even mention the other movies what followed...
Prometheus: I hate to see that human head..this head only distroying the complete mystery of the Alien and SJ universe for me...
I will go watch the movie when it comes out... And I really really hope, that the giant head was just a promotion stunt, to trick us in the wrong direction of how this movie will be ..
