I wouldn't reboot an absolutely classic, Emmy-award winning TV show.
Add to that the fact that I feel reboots are bland, uninspired and generally doomed to failure from the get-go. I absolutely hate reboots. Why re-do a sequel show? Why bother? You are not going to do it as well as Stewart/Spiner/Frakes etc etc did.
To be honest, most of the ideas touted here sound awful to me. No offens to any posters but...TNG was brilliant, it doesn't NEED recreating.
Leave the classics alone and actually create new legends. [Part of why I hate JJ-Trek as well.]
Not all reboots are bland, uninspired or doomed to failure. There have been some cases where reboots/sequels that have done pretty well (e.g. Creed, Daniel Craig's era as Jame Bond, the new Doctor Who - at least when it first started - and others that aren't currently at the top of my head).
I do feel TNG may get rebooted in some way (either as a full on reboot or cameo piece) in the future to appeal to the masses. Yes, there will be those who will want to stage a boycott or protest, but it will happen. Now, if it actually succeeds depends on the writers as well as the directors.
I feel new legends are already being paved with the nuTOS crew. I personally wouldn't mind seeing the TNG shaken up and brought up to date, since I personally find the original TNG quite boring - of course, there are those who like everything the way it is.
Sidenote: While I love the Christopher Reeves films, I realize now that they are indeed dated. I didn't exactly like
Man of Steel overall. I felt that Henry Cavill was really bland as Superman and the story was all over the place. However, there may be an actor and writer and director who actually captures what I personally felt when I first saw those films with Christopher Reeves, albeit with something extra so it appeals to the modern audiences.
Like Batman and Spider-Man, there are going to be different interpretations of the characters; some will fail and some will succeed. The same with Star Trek. I'm sure we're going to see different interpretations of Kirk, Spock, Uhura, McCoy, Picard, Riker, Data, Sisko, Janeway, etc....depending who is the 'it producer' at the moment.
Some said TOS would never work as an update. Well, here we are with a third film coming out in 2016.
