This is the sequel to the film that needed no sequel, the cinematic equivalent to painting legs for the Mona Lisa. It seeks to explain things best left to the individual viewer’s imagination. For these reasons, I hate it.
But is it a good movie? Judging by the standards set by 2001: A Space Odyssey, the answer is no. By the standards set by what tends to call itself science fiction these days, it’s ok, but not great.
