There are many guides on the internet about the correct order for watching the Arrowverse:

All of them say you're supposed to watch episodes of Arrow, Flash, Legends of Tomorrow and Supergirl interspersed with one another. So if I buy these shows on Blu-ray (I would have to in order to get the deleted scenes), I'll have to keep swapping out discs from my Blu-ray player after every single episode in order to keep watching the shows in the right order. Seems like a really complicated and unappealing way of watching some TV shows. Is that really how most people watch the Arrowverse shows or is it just the really obsessed people who watch it like that? Is there a simpler way?
