This doesn't make Clarke's work as being something terrible in my opinion but does show major differences in how Kubrick tends to create dream states, leaving his audience disoriented and noticing voids that they must fill in. Clarke tends to lean toward communicating like Star Trek while Kubrick tends to communicate with expectancy violations that are very subtle, making his audience a detective. The number of science mistakes by Clarke do not come close to the number in the film.
The Shining was far deeper than 2001 in my opinion and one can pick up Kubrick's intentions in all his films far easier by watching the videos Rob created concerning that film. It forced me to take a second look at 2001 and to pay attention with my eyes more.
Just scroll down to the following video and click on each of the short videos showing a heap of evidence of how Kubrick works. He was much less interested in reality than creating subtle distortions of reality.
