10 Once-Lovable TV Characters Who Became Completely Repulsive

In her first incarnation, Meg was like a candy apple you got from that creepy neighbor on Halloween: Sweet on the outside, but all kinds of dangerous on the inside. The actress playing the black-eyed demon initially (Nicki Aycox) knew how to balance the character's pretend naiveté with subtly sinister undertones.

It seemed unlikely that the character would be brought back after Meg's first vessel bit the dust at the end of the first season, but the thing about evil spirits is they always find a way to come back.

So fans of Meg were delighted when she showed up at the start of Season 5, albeit wearing a different "meat suit" and being played by a different actress (Rachel Miner). That excitement quickly turned to sadness, which turned to endless irritation when they saw that Meg also underwent a drastic personality change. For the worse.

Gone was the sly menace wrapped in dubious charm. Gone were the mental chess games she played with the Winchester brothers. All that was replaced with a mush-mouthed, unambiguous Bond villain who tried way too hard to project a sense of cool.

Even after she turns into an ally for the Winchesters and Castiel, it was hard to be too sad when she finally bit the dust for good.
