I go into detail in that topic I linked earlier … but essentially it is redundant and it means season\show management is mixed in with episodes themselves which messes up the hierarchy structure present everywhere else around Shows\Seasons\Episodes. It just smacks of weird decision making plus they can’t defend why it’s “better” than the current way other than it solves a problem they have with their Movie\TV service where they don’t have that Show\Season hierarchy that is there for personal media. That’s why I mention that it seems like it’d be fine for how they have their TV service setup but it’s not really needed for personal media.
It also means the first episode on the episode list is the 2nd card on the screen… feels weird.
Edit: They added “Show” to the top navigation which I think is a better solve for making navigation show\season levels easier to manage the show\season level stuff (particularly if they go ahead and add it for single season shows where seasons are not displayed).
I’ll grant that once you get watching a show you default to the most recent episode and such so it’s not a huge deal but the decision and navigation just feels so weird so it bugs me every time I see it. You’ll notice I’m usually pretty balanced even for things I get critical about most of the time but this one just strikes me super off; I rarely call something “dumb” or “stupid” but yeah, this one just bugs me and is the most likely thing to make me switch to Emby. 
That’s the bug - it’s supposed to do that but if you picked something else for the series background other than the original default then the season background (and that card and the loading screen) won’t show what you selected but that original default. It’s kinda minor but annoying once you notice it. Hopefully being on the bug report it’ll be fixed soon.
