You think this looks cheap?
Here's what I think. Basing a tv series in Nolan's universe is very, very stupid. It will not only complicate things terribly for the showrunners, but also for Nolan if he wants to keep making more films in the series.
No Gotham Central. People wont turn into a Batman show that isnt starring Batman. Simple as that. It's why Birds of prey failed (well, that and the fact that it sucked hard.) Comic fans would want it, but regular tv viewers would tune out. Fast.
Get the creative team on Angel in there. They could do it justice. Thats just my opinion.
