Basilisk is a very good anime to watch. The different type of fighting styles from each of the 2 ninja clans is very neat to see. It really is a contest to see who has the best skills among them all. Being able to infiltrate each others camps, to sneak attacks, to just plain fooling the other side thinking it's this way when it's not.
The characters were done very well to represent the type of fighting style they used as it reflected who they were and went right along with their personalities.
The story is the basis of love but the hatred from the clans makes it impossible for either side let it happen. Which is your typical story for most things. So the fighting is what's gonna make you want to watch each episode to see what all the characters can do.
