Agreed that success is not tied to the intelligence of the film. That doesn't mean there aren't a lot of us that would love to see more of a lean towards intelligence in the scripts. But there's no reason a film can't be both intelligent and successful... it just takes more effort to pull off.This whole "intelligent sci-fi" criticism about Trek movies doesn't make sense to me. Because how well-received or financially successful a Trek movie is has nothing to do with how the film's IQ is perceived. And that's important -- it's all about perception. TMP is considered a "cerebral" movie (and I do think it has interesting ideas) and it was a bomb. First Contact, on the other hand, is beloved by most fans and was very financially successful but it has as much action as Die Hard and not a brain cell in its head. It's a dumb but thoroughly entertaining action movie. So this whole "Kelvin movies aren't thinky enough" criticism just doesn't hold water for me.
And TMP was not a bomb at all - I'm surprised this idea persists even here. It was the 5th-highest grossing film of 1979. It was nominated for three Academy Awards. Adjusted for inflation, it is the second-most successful film in the franchise (see http://www.boxofficemojo.com/franchises/chart/?id=startrek.htm), second only to the 2009 reboot. First Contact is down at number 7.
It just didn't do as well as post-Star Wars Paramount had hoped/expected.
If we were to simply correlate perceived intelligence of a film with its financial success (which would be foolish), then TMP's success suggests that a return to "harder" sci-fi would be the way forward.
