I'm just starting the new season. Can't wait. For the most part, I've really enjoyed the show up to this point.
I'm legitimately surprised about the "bad acting" comment above. If that related solely to this season, I guess I'll have to wait and see. But as far as the past seasons, I feel the acting side has been mostly VERY well done. Now, if people have a problem with the over-the-top or cheesy nature of the writing, I have no problem with that. It is both of those things. And, in my opinion, it is both of those things for effect, and it works well in the context of what the show is and the Karate Kid legacy. But I get it if that isn't working for some people. But the acting? I'm sure there may have been isolated moments here and there in the earlier seasons that may not have been up to par, but nothing stands out in my memory.
EDIT: Okay, if that comment was directed toward sensei Kim and her crew, I can't overly disagree. They were definitely acted very cartoonishly. In context of the show, it was fine. But I get the criticism on that side.
