Star Trek 2009 intrigued me because it felt like the actors were excited to be there. There was an attempt. But the further out we get, the more obvious JJ's hackery is. He doesn't care about accuracy, or about lore. Doesn't care about character development, or working relationships. Doesn't care about themes, or aesthetics except "looks cool i hope(?)". Star Trek 2009 was just his bid to get Star Wars in 2015, which was the same thing;
Killing off a beloved character to drive the new ones. I agree with the others here that in general Enterprise was the end of "proper" star trek shows. But that said in regards to the fanbase at large, I wouldn't consider it to be proper star trek. In that sense, the "true end" of Star Trek to me is:
TOS: Star Trek VI
TNG: "All Good Things"
DS9: "What You Leave Behind"
VOY: Don't care.
ENT: Don't care. Nice try though.
Everything else in terms of TV or film is non-canon to me.
