From a reader:

I think Forbidden Planet does more that just “hold up well.” It can be safely called the most influencial Sci-Fi movie of all time. When Disney designed the original Tomorrow Land of Disney Land the styling cues were from that movie. The ’sound track’ from the film which was the first electronic music score was the theme music heard in the park when you visited Tomorrowland in either Disneyland or World in Orlando until the late 1980s.
Both Lucas and Spielburg cite Forbidden Planet as huge influences on their later efforts. The word “Blaster” comes from the movie. The ship had electronic shields, hyper drive and artificial gravity. Luke’s Land Speeder makes its appearance in the movie as well, driven by Robbie. If you look at the uniforms worn by the crew they bare a striking similarity to those worn by Imperial officers in the Star wars films. The house shields slamming shut were imitated in Stars Wars and other films. They even had handheld communicators. The deceleration beams in the movie look alot like the transporter in Star Trek. Tell me how many Star Trek shows began with the Enterprise arriving in a planetary orbit looking to make contact with a colony that had lost contact with Earth? And is there much poltical difference implied between the United Federation of Planets Heavy Cruiser Enterprise NCC-1701 and United Planets Cruiser C-57D? Can any of us hear Nancy Pelosi speak without recalling the line, (if we know it) “Monsters! Monsters from the Id”
And with all due respect to the Geeky-come-lately fans of “2001 A Space Oddity”, er..”Odyssey.” Arthur C. Clark and Stanley Kubrick did not invent the theme of mans destruction by his own technology. “Open the pod bay doors, Hal” does not compare to the scenes of vast underground computer complexes built by the Krell. (which is where all those huge expanse shots come from in Star Wars as well.) And what does Coopers Law about all technology being amplification have to do with black rectangles on the moon?
And Clark cannot boast that his film was based on Shakespeare’s The Tempest.
When people talk about FB, it’s about the story, the technology, the special effects, the actors. Think back to your last conversation about 2001 A Space Odyssey. Doesn’t it always devolve down to what the hell the ending meant? 2001 only holds up at all because no two two people can agree on how it ended.
