Neelix has his moments, but I appreciated his background - which helps justify it. Not to mention, the scene where Tuvok, after a mindmeld with Suder that went wrong, strangles him is so popular that YouTube automatically adds the remaining words by the time the first syllable of "strangles" is typed in for the keyphrase "Tuvok strangles Neelox". So he's clearly not that bad...
(the acting of it's pretty great too...)
Now on the other hand (and I wish I was a species that had three of them as they'd come in handy at times but that's not important right now), Wesley Crusher - particularly in season 1 and a few certain outings post-season 3 was true cringe.
Vic Fontaine was invented late in the series, has no grand purpose - apart form belting out some goofy Troi-esque advice trope that just fell flat*, and proved there were characters far worse than the proverbial lovechild of Neelix+Wesley. It's also amazing that he wasn't in the baseball episode...
* IMHO, a computer telling a person how to emote is
a tad ludicrous incredulously cringeworthy, responding to a query of prerecorded datasets and is more likely going to be inaccurate compared to an actual biological gooey being, but YMMV... sometimes the dataset can be accurate (but not always complete... like when two people otherwise agree that "too much dessert is bad" but neither will have the same reason as to
why... especially if the doughnut's been out for long enough and some ants crawled on it, ate tiny bits out of it and then put their droppings into it (in either order), and the other person had nary a clue all that happened - what, there's only one possible reason that too much dessert can be bad for your health and that's not the one? Drat...)
Granted, Q Jr (??!) from VOY was impressively horrendous a character idea as well. I never cared for the "Let's make the Q Continuum 'accessible and more easily explained' by using everyday allusion" - which quickly turned into a bizarre version of "The Dating Game"/"The Newlywed Game" for no reason, and apparently making a omnipotent baby via old fashioned squishy means will somehow save the day. Uh, okay... On top of other bizarre scenes... (that aside, the rave scene was admittedly amusing... the tribunal scene just proved VOY was running on fumes by then too...)
