You know, I am a bit ashamed to say that I don't really notice the acting as it is rather obscured by the looks. He doesn't have the most amazing range, but he does comedy very well.

It annoys me that the subtitles on the professional ones are so much worse than the fansubbed ones. And you can never tell what you're getting, though usually the back of the box is a good indication, though that doesn't help on ebay.
