You're all welcome for the heartbreak up in here.
Personally, while I still have yet to fall in love with Legends (still catching up), and even though it is sometimes frustrating, it's definitely still enjoyable and I think moving it will only benefit it, since there are quite a large sum of people who only watch Supergirl or Flash or Arrow, whether it be out of not wanting to have to watch ALL of these shows, or out of general lack of interest. That show the CW has currently on after the Flash is something I never would have watched by choice but it caught me off guard with lots of shirtless guy scenes as soon as it started so hey, if they can do it with that show, Flash will probs help Legends ratings boost (and so that way it won't get cancelled because this is probs the most diverse hero show I can think of at the moment).
Lol, we don't want heartbreaks here! We want love, love and more love!
And agreed. It'd help out both sides of the shows, really.
