Good game =/= good sequel. BG 3 can be a phenomenal game in its own right and a poor followup to its predecessors. IMHO the way the legacy of the Bhaalspawn is treated in 5e and in BG 3....and the way certain returning characters are treated, not to mention the extremely loose way Larian plays with the lore of the setting (whether you are talking about 2e or 5e, there are definately numerous liberties taken here) is pretty good grounds to demonstrate the validity of that position.
