True, the intro was cool... not very "classic high fantasy", but quite a ride.
Honestly it didn't need to be 'classic high fantasy' to me. Once you get mindflayers involved that notion sort of gets thrown out the window, I feel. Because mindflayers are more akin to lovecraftian fantasy than anything. But I honestly just love dragons, and there aren't enough high quality sequences where they're the 'good' guys. so it made me very happy to see them ripping up and burning that ship.

You kidding me? We saw a Githyanki raiding party riding red dragons taking down a mindflayer Nautiloid, in the midst of a raging Bloodwar battle: You can't get more D&D then that! It hit's on every iconic setting, from Planescape to Spelljammer. The only thing missing from it, was Elmister, and the Seven Sisters blowing up a Netheril city in the background.

Still, for a "fresh" start to a new Baldur's Gate story, it was a bit much... then again, BG3 also kind of is a sequel to Descent into Avernus, so I guess it was fine.
