TV characters you hated?

[Trevor]

Herbert Sobel, BAND OF BROTHERS.
Doris McGarrett, HAWAII FIVE O.
Walter White, BREAKING BAD.
Tony Soprano, THE SOPRANOS.

[Sitting Duck]

Captain Lochley on Babylon 5. She was an obvious eleventh-hour replacement for Ivanova who never integrated well into the series. Even her two appearances on Crusade were lackluster.

[Alex]

Kristi hated Joffrey in Game of Thrones she refused to watch it until he'd been killed off.

She then didn't watch it because of the amount of plot she'd missed.

[Rev. Powell]

Everyone on "Married with Children"
Everyone on "Friends" (except Lisa Kudrow, for some reason)

[Trevor]

Serena Southerlyn, LAW AND ORDER.
