I have to come out and say this anime IS NOT FOR EVERYONE. But if you are into this type of genre it is one THE best shows. It is based of an amazing and popular play in Tokyo so the funding seems to be top dollar considering universal japan was involved. I really enjoy the bits of random humor and of topic and out of place lines or object thrown in to get a laugh. Even though humor is prevalent the plot is amazing and the music is just plain awesome. The characters actually have levels unlike so many anime out there where everyoneis typecast. There is some filler and the plot is dragged at some points but not enough to anger anyone it usually lasts maybe a tenth of an episode.
I highly recommend it. I can't shower enough praise on this work.
