It does make me wish that in some ways, that they could've done something with the side of the Pets facade facing the Hilton (as they could've done a mural piece in some regards, similar to what they have on the Universal backlot), but part of me suspects it's more because that it's more to where the end of the guest-reach will be from Pets and Despicable Me to backstage now.
Could they of done something? Yes, and I do think the mural would've been simple to do. But knowing that it's likely backstage space, I'm not as upset with it.
