We must be about the same age. Manimal, Automan, and Misfits of Science were my jam. Also stopped liking the X-Men once the Mutant Massacre started because I didn't like the stories, art, or characters anymore.
I also enjoyed Manimal, Automan, and Misfits of Science which were cancelled too early for my tastes. At least we got 3 seasons of Greatest American Hero. I also wish Battlestar Galactica lasted longer, supposedly the ratings were very high but it cost too much to produce. I liked Buck Rogers but it went off the rails pretty quickly.
