The first episode of these shorts dropped around Halloween 2021. Rather than release them one at a time, they were bad enough that Epic and Universal finally just dumped the entire series out all at the same time at the end of February 2022.
The problem is that these are "episodic" shorts that are less than ten minutes when watched together. Each episode can't be more than two minutes each. These are all style, no substance, and frankly, the style isn't even very good. There's next to no characterization or any indication what's going on, or why, and the acting is often barely passable at best.
The Bride of Frankenstein is apparently saving the other Universal monsters from fate, but why she knows their fate isn't explained. All the monsters now have weird origins, too, like Dracula is having Chinatown gang war with a cybernetically enhanced Van Helsing. And there's random references to Fortnite lore, for some reason? None of it is cool. It's just random and flat.
What this feels like is a promo for a set of Fortnite skins that never came to be. Fortnite received some Universal Monsters skins for Halloween in 2021, but they were the classic takes on Frankenstein and The Mummy -- which look nothing like they do here. At the same time, Fortnite also received a skin for The Bride of Frankenstein from this series of shorts. If I had to guess, more skins were planned from this, but somebody along the way realized how terrible the shorts were, and by then it was too late to cancel production. Instead, Epic sat on the remaining episodes for almost five months, hoping nobody would care anymore.
Basically, this whole thing is just a crummy commercial for Fortnite. That you watch inside of Fortnite itself.
