ALIEN, i love the mistery, terror, and the gigerezque elements, tha characters, good performance, the design of the alien, very biomechanoid, i like that.
secon place aliens, yeah the action is good and the surprise of the queen.
third place A:resucrection, i like the gore and black humor of that movie.
last place alien3 i know the production troubles and the foking stupid ideas by fox, poor fincher, but i dont like a3 so much, the special edition is better(except the ox bursting) but i still preffer the others.
