They're fundamentally different franchises. Despite my long standing obsession with Doctor Who if I'd been claiming that the films had been "too much like Doctor Who" - that would be a complaint because just because I enjoy one particular style doesn't mean I want it taking over all my potential viewing options. The clue is in the names, Star Wars - emphasis on the battles and the conflict, Star Trek - emphasis on exploration, new ideas and discovery.I've never understood why people say the Abrams films are "too much like Star Wars", as if Star Wars is some sort of insult? (Well, maybe Episode VII)
The Abrams movies always felt to me like the work of someone who never really enjoyed Star Trek and so tried to turn it into something that he did like.
I don't mind the Star Trek movies existing - but I don't want the franchise going down that route permanently, especially when we look to be getting out fill of Star Wars for at least the next decade.
