Will Schuester, Glee
When Glee began, Mr. Schue was a three-dimensional character, a well-meaning but yearning guy stuck in a bad marriage who'd never quite made it and who found new purpose guiding the kids in the glee club. But no cast member has been more ill-served by Glee's whiplashing plot and overabundance of characters than Mr. Schue, who has been reduced to uttering saccharine clichés while making earnest faces: "I know you can do it!" "I'm so proud of you!" "That's not what we're about!" Were it not for Sue's jokes about his hair, we would hardly miss him.
