An excerpt:

The visuals are delightfully Seussian, all curves and slants. I loved the mitten-shaped windows on one of the houses and the way that Whoville’s Christmas decorations make it look like a captivatingly intricate gingerbread village. In contrast, the Grinch’s mountain top lair is bare and cavernous, empty and solitary, far from the warmth of the Whovian homes.
…
While this is not especially inventive, there are some clever parallels as the Grinch and Cindy Lou each have to come up with a plan for Christmas Eve. They write out their schemes with the same two words alone on a huge surface: “Santa Claus.” And both must assemble helpers and equipment without anyone finding out.

The smaller details are the most fun, especially when the Grinch brings on an enormous, yak-looking reindeer named Fred to pull his fake Santa sleigh. Or when a relentlessly cheery Whovian (Kenan Thompson) with the fanciest Christmas decorations in town keeps insisting that he and the Grinch are best friends.
