This thread did a poll on people's favorite companion, that also shows us least favorites as well,
Not really as you can just vote on one. Even if 65 (made up number) people would have Jaheria as their second favourite, she would still lose out since she's the number one favourite of few. We'd need a real least favourite poll here instead.
Personally I like most of the companions, and I do not get the Wyll hate. I think his problem is that he is a bit underwritten (I preferred his EA version and would have really liked to see a zero to hero story with him), but he is a delight together with Karlach and one of my go to companions for good runs. I can understand if people find him boring, though.
If I had to pick one least favourite I'd be hardpressed to choose between Minsc and Halsin. Minsc because I never found his schtick funny, not even back in the days in BG1 and even if he says some funny lines it gets grating after a while. Act 3 Halsin because of the sex pest issue and the bear thing, which is sad because his VA is really great and I liked the doubting Archdruid stuff with him up to Act 2. I wish they would have kept his backstory that tied in even more with Act 2 and the glaive in the druid grove.
