Typically because when you don't understand the language, you automatically assume the actors are conveying the emotion as genuine and realistic as they can. Non-Japanese speaking people like myself can't judge their acting skills because of that.

But hey, maybe someone here on the wiki does know Japanese and can say whether this is good by their standards. I'd be curious to know even though I don't plan on watching volume 1 twice.
