It’s early yet, but not one defender of 2001 has written me. Meanwhile a lot of folks are nominating Forbidden Planet as a movie that holds up. I’m a bit fond of Robbie the Robot (who had cameos, I believe, on Lost in Space and the Twilight Zone), but I haven’t seen it in a while. If I recall, they could have used more sound effects (though they had more than Lost in Space which had a sum total of one).
