I really think this whole reboot is just DOA. A lot of people are seriously superhero fatigued out with Marvel. I bet a majority of people who follow the the MCU haven't bothered with the TV shows, or have only watched a handful of the many available.
Now DC want scrap everything that came before today, screwing over the fans of those particular movies and those particular actors etc, and try to emulate Marvel's current model right out the gate, instead of establishing concrete foundations with solid, well-written and well-marketed movies to (re)introduce all these new characters, and then flesh things out with more in depth shows. The prospect of having to invest 800 hours to follow a story just seems like a chore at this point.
