These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Rover Dangerfield
Awesome Art: Probably the only real high point of the movie is the animation, which is really good in some parts
Dude, Not Funny!: Rover and friends treat Rocky being dragged away at the end like a joke, even though the guys dragging him away are pretty obviously with the mob - meaning Rocky's about to get killed.
Ear Worm: "I'll never do it on a Christmas Tree, a Christmas Tree, a Christmas Tree..."
Uncanny Valley: Rover's eyes seem to constantly stare into space, just like the real Rodney Dangerfield. Thing is, instead of looking funny it looks... off. Also, Rocky was drawn with a sort of "hard edged" look, giving him a drastically different look from the other characters, and making him look like a ghoul.
What Do You Mean, It's for Kids?: As you can see under "Executive Meddling", this movie was originally intended for adults. Suddenly the scantly clad showgirls, the mob hitmen, the turkey's death and perhaps the Christmas tree song make a bit more sense.
