I thought "Star Trek" was a fine standalone title for JJ Abrams' 2009 film.
But if you're referring to it (especially here) you have to add a additional identifier so people will know which movie you're taking about.
Star Trek Eleven, or Star Trek '09, or the one before the last one. Otherwise the people you're taking to won't know right off which movie you're referring to.
Even you had to add "JJ Abrams' 2009 film."
At some point George Lucas added "A New Hope" to the title of Star Wars. While I don't really except it, maybe one day Mr. Abrams will add a official something to Star Trek Eleven.
If only for the convenience of the fans.
