Boring Invincible Hero: Drizzt sometimes comes off as this due to the fact he almost never loses, even against the equivalent of Balrogs. The fact Drizzt is unable to defeat most of his problems (like Fantastic Racism) by simply using his scimitars, though, keeps the books interesting.
For some, the Dark Elf Trilogy (i.e., the prequels to the first novels), showing more of dark elf society and giving a real look inside Drizzt's head with the first essays, were Growing the Beard. For others, the loss of the more devil-may-care attitude from the Icewind Dale Trilogy in favor of what they saw as Wangst was early-onset Seasonal Rot.
Legacy of the Drow seemed to be more of a downer than the other books, featuring the first death of a Companion, a lot of tension between the characters and years-long separations, while at the same time putting characters in holding patterns for long stretches (for example, Catti-Brie and Drizzt, the resolution of which wouldn't even occur until the end of the trilogy after the next one). But the characters seemed to behave with more maturity, and the implications of some relationships were explored in-depth.
Paths of Darkness continues the trend of dealing with darker and more mature topics in a more ambiguous fashion, allowing yet more arguments from people who prefer different spots on the Sliding Scale of Idealism vs. Cynicism...
And so on down the line.
Strangled by the Red String: Cattie Brie and Drizzt struck many fans as this due to the fact the latter had known her since she was a child. Quite a few thought she was closer to being Drizzt's DAUGHTER rather than lover.
Strawman Has a Point: The parallel between the bigotry Drizzt suffers and the bigotry people of color in real life suffer doesn't quite hang together. While the racial stereotypes (of savagery, sadism, demon worship, etc.) attributed to real-life people of color are bullshit, 99.9% of all drow really are malicious, sadistic, demon-worshipping sociopaths who will enslave, sacrifice and kill any non-drow they can get their hands on. In this context, the nasty reactions Drizzt encounters from humans and many other races is at least understandable, considering that they don't know him and initially have little to no reason to assume he's different from his kin. Once Drizzt starts proving himself, however, the humans and others start treating him better.
Stupid Evil: The drow really come across as this what with numerous instances of their greed and ambition coming back to bite them, their inability to band together at critical moments disrupting any important venture and their constant feuding getting so close to endangering their race that Lloth herself had to come in and force them to stop. It also doesn't help that the more successful (and alive) drow tend to avert the Chaotic Evil alignment if they aren't outright good.
Word of God: Ed Greenwood has mentioned Artemis and Drizzt are two of the Realm's top ten swordsmen despite their relatively modest (By Realm's standards) levels. It should be noted, however, that there's no indication R.A. Salvatore had anything to do with Drizzt's or Entreri's stats in the sourcebooks.
