Ninja Slayer From Animation Review (Capsule Computers)

"Ninja Slayer seems like a one-trick pony at first, but it does not fail to be entertaining. In fact, the opposite is the case. The frequent insane action and nonsense, combined with an over-the-top fun English dub, make this a great series to watch. It is best enjoyed one episode at a time, however, until stories start being stretched out across multiple episodes."
