TOD:
While I caught an episode here and there during the initial run, I wasn't a big STAR TREK fan until NBC began showing reruns. And even then, the real fascination didn't start for me until the syndicated reruns (I was one of those who went orgasmic when Paramount required that stations broadcast the show complete and uncut.) I was never a real Trekkie, though I did subscribe to the official newsletter for a time and I did build and display a model of the Enterprise.
I was bored with ST:TNG in the first season because it seemed only interested in rehashing the concepts of the original series, but as it began to develop its own personality, I gradually became a fan. But I could not get into any subsequent show--DEEP SPACE 9 seemed to have no focus, I dislike Kate Mulgrew too much to ever watch VOYAGER and ENTERPRISE just never entered my radar.
As far as the movies are concerned, I was bored with the first, enjoyed WRATH OF KAHN the most and was just okay with the next two but then my interest petered out. I'm pretty sure I never saw another ST movie after THE VOYAGE HOME.
