I do have problems with NWN2, but the ones you mention totally boggled me. The controls are very good, in my opinion. The dialling system you appear to have liked in NWN1 confused anyone who didn't know already where to go, whereas dragging things from your spellbook or character sheet seems entirely intuitive.
Character background struck me as being light years ahead of NWN1. Yes, they go into less detail in some, but am I the only person who was bored to tears with Aribeth's supposed backstory? One of the few things I enjoyed about completing the OC was having the chance to shut her whining face once and for all. NWN2 on the other hand actually has engaging characters. Peripheral NPCs are just that, peripheral. I care about my chracter party, and maybe the main opponent. I don't want reams of information about Lord Nasher's childhood hobbies; I want dynamism from my compadres. Which you get in spades in NWN2.
The one thing I might agree with is the inconsistency with how death is handled. I can't revive people I like even theugh I have spells for doing precisely that, and when I have an NPC I despise polluting my team I have as much chance of shifting them as I do of shifting some sort of horribly disfiguring facial wart. Which is how I generally feel about some of them.
By and large, though, I'd recommend NWN2 to anyone, as being of comparable strength in surprises and storyline to BG.
