Grandma Got Run Over by a Reindeer

"Grandma Got Run Over by a Reindeer" is a novelty joke song, I have no clue how ANYONE actually thought it could hold up a whole movie. And then you watch it, and you realize that in spite of the inspiration, the plot is REALLY about how the only competently intelligent person on the entire planet is apparently a 10-year old boy, who has to deal with the fact like all smart people he will be constantly ignored at every opportunity until everything has spiraled so far out of control that nobody can ignore the issue anymore. Uhhhh beyond everyone in this movie legitimately having negative intelligence, it's also butt ugly, has constant animation errors, seemed to fuel itself on strange plot contrivances and plotholes, and features bar-none the worst collection of songs I've ever seen in a holiday special. This is the kind of movie where while watching, you'll legitimately be constantly swapping between unhinged laughter, ungodly boredom, and the worst case of stun lock a film has dealt to me in recent memory.
