The viewer is dumped into a full fledged world without context, which would be fine if any of it was explained before moving on to the next item on the list. Too many concurrent storylines are thrown too fast, poorly explained, and never given time to develop in early episodes. Episodes appear to jump forward and backward in time (are they flashbacks? They might be. We don't know.)

If you want to see the main character (who does amazing given what he's working with) do top-notch fight choreography, watch this. Otherwise give it a pass.
