I watched it last night and really enjoyed it. I think most of the changes are great. The flipping of support for the Hood between Detective Lance and Laurel is interesting.
My only nitpick is the graveyard scene. Who the hell goes to a cemetery dressed like that? Laurel's dress was bright enough to wake the dead. Ollie was there in sensible everyday clothes and Laurel looks like she was getting ready to be a an escort for the evening.
