And you know what? I've managed to come up with interesting stories based on ideas from episodes I disliked. Just because a character or idea originated in an installment I thought was bad, that doesn't mean it can't be the basis of something worthwhile in a different context.
Hell, I once used a character from Star Trek V
. . . and, as far as I know, nobody threw it across the room because it was "contaminated" by the worst Trek movie ever!
