I didn't care much for Throne of Bhaal, but those ending slides are a reason I always include it in my BG1&2 playthrough.
It has a bad reputation for being a power-player-fest climbing up to absurd levels of powers that adds very little in terms of narrative and exploration, but I can't genuinely say I've ever gave a shit, since I always had a blast playing through it.
The new "mega dungeon" was fairly good as well.
