I really like the art in this series, but the story is a little sparse. There is so little text that you can get through each issue in about a couple of minutes, and none of the characters are really fleshed out. Many of the events of the series would have more impact if more time had been spent developing the story and characters. For instance, when one character dies, there's no reason to care since he had just been introduced within the same issue. The revelation of the identity of the main villain is treated as if it's a big twist, but this character had literally only been seen in a couple of panels half-way through the series, and was never mentioned again, so the dramatic impact was negligible.
If I had bought these at the original price of $3.50, I would have felt that they were a bit overpriced, but the art alone makes them worth the current $.99 price. (Also, they'd be good for kids.)
