Who cares if it's made by AI and has obvious mistakes? It's not the new Star Wars movie where it's expected to focus on VFX issues. It's an ad - a 30 second clip that will run for a while to get people to buy products. If you can make an ad with AI for less money, why do it without AI?
As for the message - we need more of this. It's kind of a taboo to hate Christmas, but I loathe it and everything about it. And so do many people. Maybe they won't say that in the office or around religious family members, but we do exist.
You can't escape the shitty Christmas jingles that start in late November in almost all stores. You can't escape The tacky decorations, especially the blinking lights. If you mention the wasteful spending of taxpayer money on city decorations, people look at you as if you're crazy. You have to fight the implied obligation to participate in the celebration and to exchange gifts; having to tell people not to buy me anything. And the religious aspect of it, even though it started as a pagan holiday - people showing off how Christian they are even though a lot of them only remember their faith in twice a year. And finally, the commercialization of it - corporations pretending to care about it while trying to make everyone buy more products...
