Conceptionally I’m all for it. There are even series that have LN, Manga and Anime, so we could do a 3 medium thingy in theory. It’s just becoming a huge tie investment at that stage, so maybe keeping the scope small for the first time would be a good idea. Like looking at just a specific high-profile scene from anime, manga and LN.
I often read the last chapter (or the last couple pages) of the previous book to remember what happened and look up my notes here when I’m unsure whether I liked a series or not. Tbh, most of the series I read are just mixing together into an incoherent isekai blend in my mind.
