It is a crazy odd roll out that is botched in some respects.
For instance we have Spectrum at both places and HBO, so we get it free.
If you have Comcast however, and have HBO, they have not struck a deal yet, so you would have to pay for it still.
As a comcast subscriber who already has HBO I will not be signing up anytime soon. Hoping they work something out, but if the interface is as bad as the branding has been then I think I want to wait a while for them to work the kinks out.
Right now, what is the main piece of IP they plan on having? The Snyder cut of Justice League
