2001, call it a classic with its effects. But it takes hours to tell what is at most a 45 minute story.
This film is not about "efficiency" in story telling. Not at all
Yeah, I don't agree that 2001 would be better if it was cut to 45 minutes.
But I still think it could be improved by a few trims here and there.
Part of the problem is that it's no longer 1968, and people are watching it today in a format for which it was not designed.
My Dad saw 2001 the year it was released, in 70mm, on a Cinerama screen at the Indian Hills Theater in Omaha, Nebraska. He assures me that it was mind-blowing.
But after forty-two years of space movies, it has inevitably lost some of its impact, especially when viewed on a TV screen.
