I'm still new to all this: Where exactly is this "On Demand" content at on Sling TV?
Good; that was the missing piece. The cloud DVR is the best thing about Vue though; Sling still needs something similar.
For me: I just don't want to stay up till past-midnight to watch Toonami. If those shows are available "on demand", for $20 a month, in a format similar to Hulu, I may be content now with this service.
