Worf was a great addition to DS9, come on!
Meh. If he had come onto the show, sat in the background, and did his own thing without making too great an impact on the other characters or the show in general I could’ve lived with him. But with him came Klingon-centric stories, and I hate TNG+ Klingons. Then he got into a relationship with Jadzia. Beautiful, intelligent Jadzia, settling down with a dumb slab of meat like him? Blecch. He should’ve stayed with Troi and she hooked up with Bashir.
