I will admit this first: The Law of Ueki is not well-written. Characters do things that are entirely contradictory because of the mechanics of Shonen, characters gain powers out of thin air, half the rules of the world contradict themselves, and the voices are rather grating. HOWEVER! The series does have some of the most amazing battle scenes I have ever seen. Truly this is a series that runs on Rule Of Cool. So turn your brain off and appreciate this series for the excellent string of boss fights (á la Tony Jaa) it is.
