Adaptation Analysis
Spoilers for Fantasy High and for the Fantasy High comic.
I think first and foremost for fans of Fantasy High, we have to acknowledge that this isn't just an adaptation, it's an adaptation from an audio medium to a visual medium. The analysis video Lost In Adaptation: The Adventure Zone explains it a lot better than myself if you wanna give it a watch, but basically this is a different ballpark than adapting a book to a movie. A book gets the benefit of having descriptions of settings, designs, internal monologue, that the adapter can work with for a visual movie, they have a guide to get everything as close as possible.
But Fantasy High, all we really get is hilarious voice acting and some art designs of the cast. That's it. That's just dialogue and any descriptions that is thrown out about the place, which won't be as extensive as a book because they are moving on with character interactions and plot. So to put that in a comic setting, now you really have to think of blocking, setting designs, backgrounds, foregrounds. That is a lot to transfer in order to touch the story, a lot to fill in the gaps with.
