Hey, DS9 certainly had it's clunkers and face palm moments. Little gremlins and Quark in drag are certainly two of the big ones.
But I'll take that knowing that hey at least DS9 was willing to take chances, and is making the effort as opposed to TNG sticking to the same formula, Voyager staying safe by not straying too far from it either, and ENT's first two seasons where things were just cheap imitations.
Yes, Neelix is the ultimate example of the annoying character. DS9 at least improved their annoying character when they realized the fans weren't liking Bashir. When confronted with the fans not liking Neelix, it's like Voyager's staff said... "Screw you! Here's -more- Neelix!"
