Its...alright. You know.
I was told by a friend it was the best thing ever, I tried watching it and yeah it was alright. The more I watched it though the more it became apparent I was watching a kid's cartoon. I would have loved this when I was younger but its just too simplistic and childish to hold me today.
That's not to say its bad of course but I stopped watching not too far in- the main characters have teamed up with some others to try and find a death staff in the hands of some bad guys or something like that? And I was never drawn back to watch it again.
