No idea if this is really unpopular or not, but I don't like what South Park did to Butters. When they first started featuring him more prominently, his extreme trusting nature and naiveté, his take everything in stride attitude, and overwillingness to help people made him South Park's best character. But I think starting with the episode where he goes to Hawaii, they gave him a hot temper and I just don't like it. Cartman has a hot enough temper for the whole show, we don't need other extreme hot heads, especially not at the expense of the best character.
