My answer to this question is kind of boring. My opinions on the characters have barely changed. This might be due in part that I've been playing since EA so I've been around both to see the datamines and make my own (ultimately right) conclusions about where their arcs would go.
I generally enjoy all companions. I think my opinion on Wyll got worse with Full Release because I really liked him in EA and I find his newer version a bit blander (I tend to dislike very nice, morally spotless characters). I already disliked Halsin in EA, and it did get worse with Full Release. I really liked EA Shadowheart, and while I still enjoy her in FR, I have to say I was slightly let down, but her actress did an amazing job and she has a lot of charming moments. I think that's about it regarding opinion changes.
