In Pokemon, it's the random criticals that I hate, but they nerfed those in gen 6, so I'm happy. I don't feel status is worthwhile most of the time (particularly in the AI's hands) as it tends to do nothing more than delay fights unless a particular strategy is developed around it (ex. Breloom Spore into Focus Punch). Given the unreliabiity of the moves (many are inaccurate) or the status itself (confusion; flinch), or the situationality of the effects (heal block; taunt, et al.) making them unworthy of one of four move slots, I do feel that many effects are a bit stupid and don't really work in a turn-based game where combatants can very easily be taken out in only one turn.
