hmmm, interesting thought...is it losing its meaning? well that can be aloaded question with no true answer. your assuming that they made animes to prove a point? or to mimick the current world trends? i With so many diffent types of anime out from ninjas to spacebattles, fan service to talking magic cats...anime is entertainment. Anime is a form of art. Somewhere it has meaning to the person who wrote the script, and those peopele involved who spend days-years to finish one series. yes in that way i think it has some meaning.
as to how it reflects the world, its purly based on which anime your watching, Jin Roh is very politcal, strawberry panic is not...I dont think its losing its passion, and neither are the people involved with making it. as for meaning in the real world, if it means some thing to you fine, if not fine, its entertainment for entertainments sake. if you enjoy it, thats meaning enough for its continued exisitance.
