It really depends on what the game is trying to achieve. I recall reading an article on smarter ai on stealth games, which unfortunately lead to an unfun experience. As a player I don't want to feel the AI is "cheating".
As an example the alien game released a few years back had both interesting yet an AI that didn't feel like cheating. In this context an AI that does intersting things is accepted since the goal is to strike fear, whereas with a modern shooter most enemies are made to bring some challenge but eventually be killed.
