Everybody forms an initial opinion of whether something might be to their liking before seeing it. In fact, the whole point of network hype is to try and influence that opinion.
This idea sounds like something that isn't to my liking. It might be to others. But simply saying "it's new" isn't enough for me (or anyone else) to say "good idea." There needs to be something that sounds interesting or entertaining.
That being said, I'm open minded. If the show airs and there are good reviews and word of mouth I'll give it a chance. If the promos look interesting before it airs I'll give it a chance. I'm merely saying that, right now, it doesn't sound like the kind of Batman series I would enjoy.
