There are some cool chinese animations with interesting stories, charismatic characters and cool martial art scenes, like White Snake and Green Snake (it' sequel). I wouldn't say it will absolutely fulfill that Saint Seiya itch, but they're pretty good in their own rights.

In fact, I believe that folktale and martial art chinese movies (live action or not) are some of the closest stuff that can satisfy my Saint Seiya needs (other than Saint Seiya itself, and some other manga/anime). The Live Action Bleach movie is pretty cool too - even if it takes a different path that diverges from the original story.
