I am a fan of Baldur's Gate 1 and Baldur's Gate 2. I am also 54 years old (I *think* that qualifies as "old") and I enjoyed Baldur's Gate 3 as well.
It probably should have been called something other than "Baldur's Gate 3" but I can understand why they went with the big juicy market signal, and it did at least involve more time in the city Baldur's Gate than Baldur's Gate 2 did. As long as you let Larian's game be Larian's game (and don't try to shoehorn it into a direct sequel to BG2) its fun.
