I can't get interested in Tav. She is as generic as you can make someone.
Not really generic. More like stipped out of defining features.
Designing custom protagonist whom player can characterise through dialogue, and designing blank slate are two different things.
Larian's "origin" design means they need a neutral non-discript core dialogue tree that can work for every character they created, which then they spice up with character specific interactions for each origin. As Tav you mostly get just neutral non-discript dialogue.
Still, BG3 is far far better due to a generous amount of race/class specific options (though I found those to be somewhat problematic as well at times) than D:OS2.
It honestly isn't too bad, but it is not in the same league as some my my favourite custom protagonist RPGs. It's unfortunate side effect of BG3 trying to deliver as many options as possible, resulting in each of those options being somewhat underbaked.
