I don't know man. It felt like 2 hours of the film was devoted to apes sitting around staring at each other until one got the bright idea to club something with a bone (of course, I was pretty young when I saw it).
I guess there is a certain elegance to 2001. But I preferred 2010 more.
If you are interested in a truly disturbing film, I recommend Metropolis. It was made in germany in the 20s and presents the view of the time the year 2000 (I think). The film is in black and white but is quite advanced for its time.
I throw in my lot and say I enjoyed 2010 more than 2001 but only slightly.
And, as one can tell from viewing my avatar, I enjoyed the movie Starship Troopers. It was extremely gory but I truly liked the Intelligence uniforms. Also, it represents a quite ordered and well-kept society - the quilty executed, citizens having earned their social status et al. (There are quite a few wrongs, obviously, but I digress...)
The ships are also interesting and the basis for my Curiassier-class Cruiser.
The movie with the Triple X star was good simply because I do enjoy watching Vin Diesel. Heh heh. The movie itself had excellent effects but a thin plot - -however, Vin Diesel had his shift off which makes up for any lapse in plot.
