I've said it before and I'll keep saying it until it happens...Robin can be done right if you take the right source material and apply it. The greatest Robin origin story I've ever read is Dark Victory. This is my favourite piece of work from Jeph Loeb. Tell me this story handled right wouldn't work in a live action piece.
Robin is still a 13 year-old that Batman is bringing out to fight crime with. It was a good story, but a live-action version of that is going to be hard to buy for mainstream audiences.
Broccoli hit it on the nail why "Batman Forever" and "Batman and Robin" didn't work. They changed Bruce and Dick's entire dynamic and aged Dick.
Actually, I said the opposite.
I think it worked because they aged him and changed the dynamic.

Okay now I remember about those rumours from a couple years ago now that you mentioned the time frame. I still don't think a live action television series is feasible. The economy is a big problem right now. Look at all the productions shutting down. I also think this is one reason why DC can't get their shows off the ground. Their concepts are too expensive to produce right now...but maybe that's a subject left better to another thread.
