Shows ruined by the college years

Boy Meets World

Extenuating circumstances to keep old characters, minus tackling mature issues, minus one of the Lawrence brothers, equals a surefire formula for destroying a television series with college. And "Boy Meets World" was guilty of all of those things. The only thing weirder than Corey and Topanga's on-again/off-again teenage wedding was the absurd lengths writers went to to keep Mr. Feeny on as their teacher. FYI: no one is qualified to teach grades six through fourteen.
