[Crazy Jetty]

No, you can never get a universally agreed "great" movie (Outside of The Dark Knight.)
But it's not unreasonable for people to hope for or expect a Good movie. "Good" being decent plot, decent characterization, and decent writing. In three TF movies, we have not met one of these conditions.
We have seen that this goal is possible. Ironman, Ironman 2, Batman Begins, The Dark Knight, Thor, Spiderman, (New) Star Trek. All are great examples of movies that have managed to be open and inviting to the general public, while pleasing fans.
They all hit the benchmarks of what all movie goers expect from any movie they pay $10+ for. Decent writing, decent characterization, and a decent plot.

Just because someone is a fan of a franchise, and you personally expect said fan to just roll over and happily except a movie that misses the benchmarks everyone universally (whether they're a fan or not) excpects to see from a movie is a virtual slap in the face. And pretty damned insulting.
