Watched IP Man last night. Good movie and appreciated the dubbing for convenience, although some of the voice actors could have done a better job. Also, a teen age kid was voice cast as a little boy. There is a clear difference between how a 15 year old sounds and a 5 year old.
Language dubbing is not bad in and of itself, it is just that the casting and directing of the voice actors are often not up to the quality of the rest of the movie. Still, I prefer to have the option vs, not and having to just read the subtitles.
