Just watched the pilot over lunch. It was.... alright.
It's very Smallville/Arrow/Agents of Shield in tone and feel. It remains to be seen if it turns out to be a monster of the week kind of show, but I very much suspect it will be. I was hoping for something closer to "True Detective" but set in Gotham, as I thought it was supposed to be this gritty realist take on the origin of the Batman Story. It certainly isn't that, it's just seems to be another superhero based, seen it all before, show. Albeit without the actual superhero.
Having said that, it was perfectly watchable, and will probably be up there with the best of these type of shows.
It does have a few issues:

When is it set, exactly? I know this is a made up world, but it's set 30 years in the past, and people seem to drive old cars, yet take photos with digital cameras and talk on their mobiles
It's also incredibly fortuitous that Gordon's first case with his partner is the Wayne murders, and in the first few days of that case he either meets directly or is part of interaction with... A young catwoman, a young riddler, a young penguin, a young poison ivy and possibly even a young joker. What are the chances, eh? Give it a rest please, we know it is set in the batman universe, you don't need to shove it down our throats every second.
