I thought Zombie Powder was great. I adore Tite Kubo's art, which is why I picked it up in the first place. It's just personal preference, but I find it stunning and beautiful in its simplicity. I read all of it in one sitting and was sorely disappointed when I found out it was a discontinued series. Even though it doesn't have a proper ending, it's worth the read. It's well paced, it's funny, and the characters are enjoyable. True, a lot of it is recycled or cliche things that you can see in most shonen work, but that doesn't makeit any less fun to read. It's just another take on some of the same old things, but it's definitely not boring because of it.
