I enjoyed this look into the "Lost Year"...I loved how it delved more into Dick Grayson's relationship with Barbra Gordon who I love, and his frustration with Bruce and how their relationship at that time, like most adults and their teenaged children, always hits a rough patch where the teenager thinks he/she is adult and knows everything and the adult is wrong about pretty much everything, but also how the adult can be insensitive to the struggles and complexities in the life of a young man/woman on the verge of adulthood.
I though it was well written and fast paced.
It made Dick Grayson more real and accessible, he is my second favorite hero next to Batman,, his flaws and missteps are very similar to those of most young men who arent' secret vigilantes, he can be an absolute pig and insensitive, selfish jerk to a former girlfriend, but he can also make some pretty good decisions showing he took to heart the principles and integrity he was raised with.
However, I found it to have a lot of sexuality, not good for younger readers, which is typical for Nightwing stories, the writers tend to give him a pretty healthy sex life, he seems to have more time for that, (or interest in it) than Bruce, who, I think, despite Bruce's tough guy, hard as nails, demeanor, he is still a cultured, aristocrat, and a mature man, who, and in the last few years is a little more selective about who he sleeps with.
Dick, after all, is still a hot young man with an active libido. So I get it.
I think its worth a peek.
