Okie dokie...
Danny Phantom: "The Ultimate Enemy": Words cannot describe MY hatred for this contrived, illogical above all overrated episode. Same goes for its equally contrived, shallow, and overrated antagonist. "Reality Trip" is up there too.
American Dad!: "Camp Refoogue": Hayley went from being my favorite character to the character I most wanted to punch in the face. I'm still miffed at her for what happened.
Juniper Lee: "Ding Dong, the Witch Ain't Dead": I hate, hate, hate, HATE episodes that challenge the status quo... and rewind it without a second thought. I really liked Jody and Ophelia... it seemed like the only time we ever saw her friends was when they were possessed, enslaved, needed blanking or "oh, we need to pad time"
Simpsons: "Kill the Alligator and Run": This episode made me stop watching the show, it was THAT profoundly stupid and unfunny for me.
Futurama: "Love's Labors Lost in Space": I was sick of Zapp's "We had sex, Leela!" jokes the, oh, eleveny billionth time it was done.
Foster's: "Foster's Home for, um, Make 'em up Pals": Oh, ha ha, Frankie abuse is so funny. And, you CANNOT honestly expect me to believe she'd be like "Oh well!" about it like she was. See "Kryten" below for "Suprise for you."
Ed Edd n' Eddy: "If it Smells Like an Ed": "..." Just "..."
I'm sure there's others, but those are the ones that REALLY get me ranting.
