I loved his early stuff, the Duelists, Blade Runner, and Alien ect... but his Christopher Columbus movie is actually the first and only movie that put me to sleep in the theatre. the pallet in all the early movies is a bit subdued- not so much in the duelists, though, but there is a tension in Blade Runner and in Aliens that held me. I didn't find that tension in KOH. I liked Galdiator well enough at the time, but after seeing it again, I kind of feel that Sparticus does a much better job with many of the same themes. There is no shame, however, in being bested by Kubrick.
I am a picky over analytical bitch, though, so take all this with a grain of salt.
