I am guessing Nightwatch is an anime? I was refering mostly to actual foreign films with live actors, no matter how good of a dub it is, it is nothing like the real thing. I feel the acting is an important part of the movie, and when I am watching a dub, I am not hearing the original actors preformance.
I really don't watch any animes or any other foreign cartoons, so I don't really know how I feel about dubs on them.
