If you watch the reaction from Mario and Karina when they lost to Emmitt and Cheryl, that left a sour taste in many people's mouths. I can remember someone in the episode saying it best, Mario looked ready with his acceptance speech and had the smug of a guy who thought he had already won. That was Karina's first season, and she was crying on ET about losing and how she thought they should have won. They didn't really have many congratulatory words for Emmitt and Cheryl right after the announcement. That was the first season I recall their being the ringer argument and the first fan war between Emmitt and Mario. It was obvious early on it was going to come down to those 2 in the end, similar to season 4 and Joey vs Apolo. That was the first case of, do you want to see a dancer dance or someone learning to dance? Looking back, I enjoy Mario a lot more now. I can't say I was entirely anti-Mario then, either.
