I probably prefer the novel 2010 to the movie. Hyams simply couldn't match the perfectionism of Kubrick, and all sorts of little inconsistancies between the two movies get to me.
Gravity in particular suffers - after the first scene of the two astronauts walking on the wall of the pod bay in Discovery people act like there is regular gravity there in a later scene. All the velcro on the floor of the pod bay and the tool locker next to it has turned into just flat surfaces. Floyd has a conversation with the Russian captain on the bridge of the Leonov as if he's in normal gravity, then he puts a pen in mid-air.
All the displays on Discovery are suddenly rounded TV screens instead of the flat-screen displays shown in 2001 (acheived through rear-projection screens). And the little "HAL 9000" sign is now lit up on all his terminals.

I like the movie, but these little things bug me when I watch it.
