While I disagree with your pessimistic take, I do agree that Wes needs someone to reign him in. When I look at my favorites of his oeuvre, they're all grounded stories with whimsy added, not whimsical stories overloaded with whimsy. Wes should add his touches to enhance a basic story, not start with over-the-top twee and then overload it until it looks like a comically-oversized (and symmetrical) Sundae.
