A certain segment of the fandom is a lot older than they were in 1977. Or 1983. Paramount has been chasing a young demographic with Star Trek as of late, and this old fan felt sort of unwanted after seeing STID.
It's unwise to forget us old geezers buy movie tickets too. And those of you lucky enough to have a family, this is going to be a multi generational experience. How often does something come along like that, except when Disney dusts off a classic now and then?
I look forward to seeing old friends reunited to save the galaxy, one last time, and pass the lightsaber to the new kids.
IIRC, there were a lot of old geezer jokes when Star Trek 6 came out, but the original cast had the last laugh.
