There's no such thing as a bad character. But when a writer creates a character and pretty much forces that character to be ultra-likable and have everything be because of their actions and to revolve around them . . . don't expect me, personally, to like it.
If someone brought Silver back, and treated her with dignity and respect, I'd be fine. But Englehart's pushing of her was annoying. I'd rather make my own judgements about a character's "likability," thank you very much.
