There's no denying that the Powers that Be has taken a big step back in quality this season. The writing is subpar (slightly improved in recent episodes), the acting is far from being the best we've seen, and the female characters do feel somewhat weak compared to the many strong female Rangers we've had in the past.
Despite all of that, Samurai has it's upsides. For one, the show quality looks absolutely amazing. I like the directing we've seen, and it being in HD makes it all the more enjoyable. I mean, there's more but that definitely sticks out.
