I've caught an episode or two and I really liked it. I wish I had more time to catch the whole series. Kind of which they'd kept John Wesley Shipp back and used him as Jay Garrick instead of Barry's dad, however.
Actually I think the one problem with the show is that it's too slow. There's too much soap opera bullshit (same romantic plot going around in circles) laced with the good Flash mythology stuff. 24 episodes is just too much. Daredevil had the right idea.
