The tv show it's based off of is pretty good. Modern audiences will find the pacing a bit slow at times but it also makes it a good time capsule into the era in which it was made.
The 90s movie was ok and didn't do anything to offend the source material. Too bad it didn't do well at the box office so the planned franchise never came to be. There's been some later attempts to resurrect it but they've been marginal at best.
