If ep.7 goes in an entirely new direction then any hopes that there is a coherent story going on is thrown out the window and its just random episodes where stuff happens like some comic book series.

Yeah, if the Sequel Trilogy was totally unconnected from the OT, you'd be right. But if the ST is about the children of OT characters (Leia's kids, for example) and what they do with the galaxy their parents and grandparents formed, how they handle having Force-abilities, etc, then it's both totally connected and not about Vader.
