The late 80s era of Gambit/Rogue/Longshot/Dazzler/Forge era of X-Men. I thought that was the most weak/pitiful lineup I've ever seen, and I absolutely hated it. X-Factor (which was the 5 original X-men) should have wiped the floor with them within minutes, other than Storm, Wolverine and Rogue only because of her strength.
To follow that, I've never liked any of those characters by themselves either, so anytime someone talks fondly of those characters or that era, I get very frustrated.
On the opposite side, there were a lot of 80s sci-fi shows that I loved growing up but they all got cancelled right away and many tend to put them down when they come up. Shows like Manimal, Automan, Misfits of Science. Might depend on how old you were when they were on.
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.
