Its so amazing to watch animation space be it movies, cartoon characters books and so on, changes coming to this space over priod of time are so fascinating, cultural fusion is number one factor which is attributing to so many changes.
During initial period of cartoon/animation industry it was mickey mouse, donald duck to so many entertaining and honest characters mostly living in a dream world and doing funny things, post world war II era gave rise to macho characters like superman, popey, batman and so many of them. For last few decades east and west culture fusion saw its effect on this industry and gave similar wester fashion characters like teenage mutuant ninja turtle and so on with machoism or so. This decade though many rules of game have changed and if we look at box office to television rating points one thing is very visible, only plain entertaining but intelligent characters with lots of extra power with politeness, well mannered and characters with both west & east see huge success. A 90's or 80's type of movie or character will fail to appeal larger kids to grownups here as we are already shifted culturally we cannot look at only one culture. This even applies to few classic creations like tintin, calvin and hobbes, garfield to others.
Most of todays popular characters like SpngebobSquarepants, ninja hatori, perman, dora and monkey, pokeman, justice league, power rangers to ice age, madagasker, happy feat to any thing, culture and fuson is very visible.
Happy watching.....
