It seems to me that dubbing companies are TOO obsessed with matching the lipflap, when there are numerous examples of exactly the opposite in the japanese versions.
sorry, the "lipflap" is what they call the mouth movement in an animated movie.
Most companies try to match the sentences exactly to this "lipflap", often resulting in unnatural pauses and intonation. In a worst case scenario this makes it very annoying to listen to a dub.
