I've kept up to date with the manga of Denpa Kyoushi, which I've really enjoyed - but I've heard bad things about the animé. Mostly about the low standard of art and not doing the manga justice in some scenes.
I did enjoy the manga, but not enough to watch the anime - unless there is any significant difference between them (in which case, I'd like to watch those segments so I have the complete story).
Is there anything major in the anime that is different to the manga? or any new characters?
