So you believe profit is the sole factor that determines the quality of a movie?
It is the only vaguely reliable scorecard that studios have. The only factor that dictates the quality of a movie to me is whether I like it or not. But I think that it's non-sense that I should be trying to pass off my opinion as objective and everyone (especially the studios) should acknowledge the brilliance of it.
If you don't like a movie then you don't like a movie. Great. But the studio shouldn't be beholden to the whims of a small group of loud, obnoxious fans who don't seem to have anything better to do than bitch about how J.J. Abrams raped their childhoods. Dozens of movies are released every year, I go to some and don't go to others. The few that I like I debate whether they're worth a purchase on home video. With Star Trek, I'll spend time debating the finer points of the movies to a degree. The films I don't like, I move on from.
