(The Huntsman, here's a comment.)
Tina is so beautiful. A perfect, photorealistic CGI theropod. I like the dark, detail-attentive lighting they give to the characters when they are trying to take the doll from Tina, along with other examples (such as characters in the car) in the clips presented---the characters blend in with the background, with the 2-D and 3-D contrast being a decorative seam. I find it notable how Gumball's mother's ears' drop when being serious. It is a nice animal-like touch. (I hope the ears of the Thundercats characters are not completely immobile; that the characters, other than the Thunerkittens if I heard correctly, lack any sort of tail is a bit of a disappointment.) Yes, the musical score is nice, and reminiscent of Pixar movies, particularly the Incredibles' jazz style.
