I'm not sure if the dubbing is working it might be better to do an entirely different dub track (including the original dialogue) all of which is to some extent out of sink with the lips (so it looks like a film not filmed in English that is dubbed).

The audience might find it easier to cope with the whole thing being out of whack than just key lines.

I think the dubbing is working fine. It matches better in some places than others but I don't think it's really an issue for this kind of edit.

I'm not going to replace the dialogue completely.
