1) Throwing too much crunch. This includes adding non-core PrCs to villains. This is less of a problem if the adventure states it is a psionic adventure or an FR adventure or what not, in which case PrC use should still be kept to a minimum. (No Red Wizard/Archmages, you hear?)
2) Throwing in artifacts or NPCs - in the former case, this is especially true if it's giving metagame benefits. An artifact is supposed to be a plot device. The latter can be handled appropriately, but often it's better not to do so.
3) Making the villain something overused, such as a half-dragon, a drow (without a good reason, anyway), and so forth.
