It would be pointless to reboot TNG. The reason it works for TOS is that the characters became societal archetypes of a sort. Kirk, McCoy, Spock, etc. They were known to people who never venture near sci-fi anything. The TOS movies also showed the final arc of these character's lives, as we watched them get older, be promoted, and die.
TNG was more of a Trek lovers fave. to do a remake in movie form would be stupid. Even a remake on TV would suck.
