I do wish ABC would get off the stick a bit. Everybody else "posts" their broadcast shows promptly at midnight. ABC kinda gets around to it, often in a day or two. Here Legends is up against SHIELD, and one gets bumped. With the Supergirl lead-in, it feels better to watch Supergirl/Legends rather than switch mind-sets to Marvel mid-stream. (Horrid scheduling, btw. Why compete with another genre show when there's easy rating pickings in a dozen other slots?)
Did accidentally flip over for one moment, and it was, of course, a giant spoiler.
I think the whole LMD part of the season would play much better sequentially, without commercials, all of a piece. Such it is destined to be, and the scheduling may spell doom.
