NYCC had a rather ingenious way of getting people into this panel. Put it right before the Walking Dead panel.
They showed the first two episodes, and I really liked them for the most part. There are some of the traditional CG complaints (streets need actual people) but strong acting from people like Kelsey Grammar and Ron Perleman and an interesting premise take what could have been a fairly standard henshin hero in high school plot and really elevates it.
