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: Grandma Got Run Over by a Reindeer
Adaptation Displacement: There's quite a lot of people unaware all the songs in the special are a huge chunk of the other Dr. Elmo Christmas songs.
The ET reference that lasts for all of ten seconds when Jake meets the elf in his room.
Dude, Not Funny!: At one point during Jake's search for Grandma, Daphne actually tells Jake to give up looking for her in probably the coldest tone ever. It's pretty jarring in an otherwise family friendly movie.
Fridge Horror: If Grandma hand't been run over by Santa, she would've brought those tainted fruitcakes to the community center and who knows how many people would've gotten sick because of it?
Idiot Plot: The excuse that Santa gives as to why he didn't bring Grandma back is because since she has amnesia they don't know who she is. That is a really crappy excuse seeing as how after they made sure she was okay, they could've just come back to the same spot she was run over, and asked the people nearby as to who this woman is. Instead he just leaves her at the North Pole for an entire year, and apparently during that whole time doesn't check missing persons reports to try to figure out who she is. Kind of makes you wonder if the court was right to let him go.
Could Have Avoided This Plot: Santa didn't have to take Grandma to the North Pole anyways. He could have called for help note it's not like he couldn't; his identity or existence doesn't have to be secret or unknown, considering that he doesn't hide the fact that he's Santa Claus once he brings Grandma back to Cityville or just left her there and the family would have found her on the front lawn within minutes & gotten her medical attention at a local hospital, where they'd at least know where she was. Instead, he abducts her and leaves a note like he had dented someone's car, not run down an old woman.
Moral Event Horizon: The fact that Cousin Mel was perfectly willing to poison innocent strangers just to get Grandma to sell the store put her over the line.
So Bad, It's Good: The voice acting sounds, at times, incredibly stilted and several characters were given actors that aren't well-suited for the part; the jokes and puns are almost always groan-inducing; and the animation isn't anywhere near as fluid as it could have been. Even so, it's really hard to dislike this special, Adored by the Network notwithstanding, mostly because of issues with the production.
It doesn't hurt that Cousin Mel is incredibly hot.
What an Idiot: After spending so much time with an Amoral Attorney, you'd think Cousin Mel would know better than to just suddenly confess literally EVERYTHING.
Possibly justified, as Cousin Mel is pretty much It's All About Me personified. Naturally the moment things were turning against her, she'd confess to try and get a lighter sentence.
Not to mention all the evidence against her.
She was pretty much boxed into a corner at that moment, so what else could she have done?
Well, for one thing, she could've refrained from telling the court of details of the evidence against her that had not even been uncovered yet. Anyone with a ounce of common sense would've conferred with her lawyer before saying another word.
