Mermaid Saga

I didn't like this 13 episode anime, I guess because I thought the story progression was boring, and also it's extremely violent and bloody (and the blood looks really dumb). It's about a man that's immortal because he's eaten mermaid flesh, but the flesh usually kills the eater or turns them into a monster. He meets an immortal girl and they go on a journey together. The last episode is by far the best, and also the scariest, not for the ending of the story but just in general. The last two episodes were apparantly too violent to air on TV, so if you have a weak stomach or a faint heart, think twice before watching this (and apparently the manga is even MORE violent). One out of five stars.
