I liked everyone of the movies i liked. most favorite would be Howl's Moving Castle, Castle in the Sky, Spirited Away, Nausica - valley of the wind. Have yet to see grave of the fireflies and tales from earthsea.
I dont mind, and i welcome it if the plot gets too boring. Maybe producers put fan service into anime more now, since they get to put more steam and leaves and bats and do creative censorship into the tv version and make people buy their dvds just to get a glimpse of the bouncy stuff in all their glory on dvd. Its just another trick to sell the dvds and other merchandise.
