I like TOS
Klingons, even up through the movies, way
more than TNG
Klingons. I even like their look better. Admit it -- those stripey shirts and sparkly pants were snazzy.
I'm not sure this is unpopular, but I absolutely hate
the "V" on the foreheads of TNG
Romulans. It was a damn plot point in "Balance of Terror" that the Romulans looked just like Vulcans, and with that big "V" on their foreheads they look no more like Vulcans than whatever forehead alien of the week looks like Humans.
(2009) is a fun movie to watch, but kind of sucks as a Star Trek
movie. But the whole alternate timeline deal was sufficient for me to accept the changes within the context of the movie.
I don't think TV Picard and Movie Picard even seem like the same guy.
I think that by the time of TNG
Gene Roddenberry was buying his own hype and Trek
as a whole suffered for that.
