As a huge Batman fan since I was a kid (39 now) I had always known of Bill Finger and his contribution to the character so if you are a true fan a lot of the first half of the doc won't highlight anything you didn't already know. However the second half which tracks down his existing family and the fight to get him officially recognised is worth sticking with it. On the downside I do feel it drags in places and some of it is quite dry but overall it's something every Batman fan should watch.
