In the artigo that I just read(even I was still in this fansite), everything what I just read that the episode of the show was similar with one of the another, but the different is the plot and the cast that be put into it. It's not like I said the show was boring or something, but at least try to put an element of surprises in one episode. Not much but just one.
For example, make a new character that was Ben new rival. Which he was not an alien or have a super power, just an ordinary person who was smart, good in martial art, really good looking than Ben was, and etc.(If you know what I mean)
Well it just a suggestion. No hard feeling for Ben 10 fan, because I am also a fã of BEN 10 AF@UA.
