Well it is an adaptation of 5e, it is turn based because that's how D&D works, and your character portrait is whatever your character actually looks like. You custom design your character's actual look and that's your portrait.
So if those are deal-breakers, then no you're not going to have a good time.
But if you can cope with those, then I'd say this is a worthy successor to BG1/2. I've enjoyed the heck out of it and have played since early access and I'm still playing it and trying out stuff.
