My order is
Aliens
Alien
Alien Resurrection
Alien 3
The reason I prefer Aliens over Alien is because I like Sci-fi action/adventure movies for then sci-fi horror movies.
I thought Alien 3 was a load of garbage, I'm okay with them killing Hicks, Newt and Bishop, but their deaths should have been handled alot better, also the characters in Alien 3 are nowhere near as good as the characters in the first two movies.
I guess Alien 3 is a fine movie overall, but as a sequel to Aliens, its terrible.
And alot of fans seem to hate Resurrection, but I actually like it, pretty good movie until the Newborn comes in.
