Best in terms of quality or one I like the best? Gladiator for one I like. Quality I'm not sure as Aliens grosses me out and Blade runner is super disturbing so I never really enjoyed them. Hard for me to consider the best movie as something I hated. Also for me, emotional reactions are a big factor, and few movies make me react like Gladiator does. That movie is poetic! Alien and Blade runner just make me feel sick to my stomach.
