What can I say that as not already being said! I can say I have just been blown away again by this movie. After watching it on 4k Blu-ray, seeing details I have never noticed before, appreciating even more all the work that went into it.
There as already being a lot said about the film in these reviews, but I just want what to say, something about the negative reviews. There is a trend with them, they almost all say the movie is too slow. Its a movie to relax into and take in the visuals, a journey into space is going to be slow, it gives the movie a feeling of the vastness of space. Not every film as to be about none stop action.
I can say that Kubrick was a true master of his art and I doubt we will ever see another director like him.
