Iīm not saying OPM is not a parody, please read more carefully. From the beginning I said that without the ridiculous origin of Saitamaīs power, we could very well watch this anime as a parody OR a serious shounen show. Both works. Thatīs why scenes without Saitama donīt necessarily feel like parody, because thereīs no element during that time that wouldnīt also work for a serious shounen-show. Again, see Boku no Hero no Academia. It also has a lot of parody characters (the shining savior that everyone admires), but I donīt see people call it a parody anime. It could be one. Along the same lines, give us a proper explanation for Saitamaīs power, and you COULD watch the entire anime as a serious, albeit funny, shounen anime. You COULD also watch it as a parody. Both would work. Right now itīs leaning strongly towards parody, because the ridiculous explanation for Saitamaīs power allow no other point of view.

Thatīs all Iīm saying.
