Mugen no jûnin: Immortal

Rich, complex storyline with violence matching AOT, Blade of the Immortal does not immediately draw you in from episode 1. Stick with it, however and there are moments of anime magic.

Violence (of all types) is extreme and not for the faint hearted. Another good thing is the a good number of secondary characters whose story line develop over the season.

My main criticisms are:

• No effort to explain the background, context etc. of what we are watching, the timeline and history of the era.
• Fight sequences seemed very artificial in the beginning, even for anime. It was almost like the each fight was cut short to show the viewer the start and the end. This did improve over time.
• Too many side characters will little or no introduction to help understand how they fit into the story.
• The protagonist is too powerful and quite a few of the initial fights were very predictable / boring. This did improve in the end.
