1. At the end of "How The Grinch Stole Christmas!" (book- 1957, network cartoon- 1966) the Grinch's heart grows three sizes, he realizes he had Christmas all wrong, he returns all the toys he stole, and he even carves the roast beast for all the Whos down in Whoville. In other words, he's a totally reformed character. This ad pretends that he still steals toys and is the pre-1957 Grinch in his outlook.
This is like portraying Scrooge as a vicious, bitter old miser in modern ads (which also happens.) It makes no sense. Stop portraying former villains as current villains.* It's stupid and doesn't fit into the Christmas spirit at all.
2. This guy's frozen smile is totally creeping me out. Get that thing surgically removed from your face, buddy. You look like someone offscreen has a gun to your head.
*while we're at it, how about keeping your grubby hands off our memories period and come up with your own characters, music, et cetera?
