what really made me want to watch super sentai in the beginning, was the same thing that keeps me reading naruto.
the characters have heart and depth and there is a cool factor. to various things such as the gouraijers and abarekiller.
then mixed in with that is the odd occasions where they tug on the old heart strings.
I think this is the sort of things that keeps people interested in the sense of 'otaku' as well. this has been made very apparent in some shows like akibaranger and also densha otoko. I think it's this 'passion' that really makes a show.
I think akibaranger highlights how this passion and imagination, is the driving force behind a successful show or at least a show an adult would want to watch.
is this passion being lost?
maybe this passion is being replaced by 'enthusiasm.' .. this type of enthusiasm that kindergarten teachers bring to the table. it's bouncy, it's 'fun' but is it genuine? does it really bring a feeling of hope and positivity?
