Definitely prefer Star Trek ... although a lot of Star Trek is drek. But the best Star Trek -- City on the Edge of Forever, Beyond the Stars -- is among the best scify in any medium in the modern era --- much of the rest is good space opera -- Yesterday's Enterprise, Best of Both Worlds, the Wrath of Khan ... I think the best Star Wars (Eps 4-5 and Rogue 1) is good space opera -- both most of the rest is bad space opera.
Can I return to my love of Tomorrowland and my belief that it will one day be recognized as a great movie?
The best parallel I can find is a science fiction movie released in 1982 that was a total flop -- both at the box office (where it failed to match its $28 million budget) and with the critics that almost universally panned it -- Roger Ebert gave one of the best reviews, saying he loved the visuals, but thought the story and the characters were "thin and clichéd". It was buried at the box office by ET, Wrath of Kahn, Tron and (if you consider it scify) Poltergeist.
Ten years later, Blade Runner was recognized as a great movie -- it's consistently been rated the best or second-best scify film of all time.
I still believe Tomorrowland will eventually follow a similar path.
