For many games, enemy boss fights are the most memorable part of the experience. This is often a result of being exceptionally designed in any number of ways. However, the opposite is also true: poorly-designed fights can impart a negative impact on the player so severe that it supersedes everything else they've experienced despite how praiseworthy other aspects of the game may be. So, with that said, what have been some of your least favorite boss fights? Is the reason they're unfavorable due to being too challenging, or perhaps not challenging enough? Not being balanced fairly? Repetition? Having an intense difficulty spike? Its length? There can be all sorts of reasons for why a boss fight is bad, so I'm curious what's been most irritating and the reason(s) behind it for others.
