I can sum it up in three words-
Suspension of Disbelief
It's not so irritating when I read from the point of view of a cliche character (which Drizz't is) as when I can't believe 90% of what's happening. And then there's the whole psychic distance thing. I mean how can you sympathize with this guy? Yeah the whole thing about exile and all but man give me some depth here. I'm parched for some character development.
The action is decent, but how can it be engaging if I don't feel Tension? And how can I feel Tension if 1- the character is invincible and 2- he's an emotional brick wall. Now there is the whole Conan thing. But at least Conan was interesting- the James Bond of hack and slash. His motivations were simple- amass as much women and gold as is humanly impossible. And here you play to a vast audience- power hungry men everywhere.
I agree with the picture guy- Drizz't is just a facade for the virtuoso. Pretty on the surface, seemingly invincible. Underneath, there's nothing but sand.
Truth be told- most game characters convert to piss-poor fiction characters. If you want to make a good, engaging character write from his/her point of view first. Then make it into a game character. You'll get much more milage and at the very least you'll end up with a narrator that has some mohjo (the voodoo word for soul).
