Not bad. I thought the artwork was charming. I agree with another reviewer who said the stakes felt low. Even if they were, I did not feel any sense of urgency. In addition, there's a character conflict between Ollie and his dad's friend's son that literally gets resolved in 2 -3 panels. 

Something that's different with this Green Arrow is that Ollie is very opposed to killing any living being, human or animal. This boy was acting so scared to shoot an arrow, but great that he could hold fast to his beliefs.

Overall, this was a serviceable tale.
