Like Bloodlines I get they wanted to try something completely different, because if you are just going to do Supernatural 2.0, what's the point in watching a copy when the original is right there. Even Kripke co-signed Bloodlines. The main problem was it was too CW, and it seemed they felt like they need to have certain elements in the show that otherwise wouldn't be apart of SPN. But, there is a version of Bloodlines that could work. Wayward Sisters, that was just a bad idea from conception.
I mean, I kind of feel like a lot of the problem with Bloodlines was that it was trying to be Supernatural 2.0 except more CW and without the fundamental ingredients that made Supernatural 1.0 work? Ennis was knockoff Sam without a Dean - ostentatiously fridged girlfriend to start a revenge mission, mysteriously absent father who knows about hunting, blah blah blah. Set against the backdrop of a very CW monster mobs in Chicago premise.
Wayward honestly felt like they took a completely unconnected concept that was half Buffy ripoff and tried to shoehorn it into the Supernatural universe. Hunting is fun, the YA characters have special powers and/or are immediately amazing at everything they try, lazy stereotypes, lazy copycat Hellmouth so they don't have to give a crap about lore, blah blah blah.
I'm not convinced a John & Mary prequel is inherently worse than either of those - but nothing about it sounds inherently better, either.
