For years, I saw endless praise for "The Fairly OddParents" on the Internet, and decided that I should give it a look for myself. And then I did, and it was one of the lamest things I'd ever seen.
Of course, after that, I found out that the episode I'd watched was from Season 5, which fans have determined to be the worst season ever. Apparently, from what I've gathered, there are only a select few episodes from each season that are absolutely brilliant, and the rest range from mediocre to awful. I really don't want to have to pick and choose which episodes of a show I watch - if it has no quality consistency from episode to episode, then I generally don't bother with it.
