I'm posting this in the general discussion thread because this is less about TOS and more about Star Trek as a whole. Basically, if TOS had lasted its planned five years instead of being canceled and resurrected in movies that paved the way for a sequel series and a whole franchise of other movies and television shows, do you think it would be remembered today? Would Star Trek have expanded beyond the original series or just had its five year run, fizzled out and then be just a very small piece of science fiction history? Did the cancellation after only three seasons actually ensure Star Trek's ultimate success and influence?
