I almost exclusively watch foreign movies because I don't really like german cinema, it's most of the time boring and lacking in many ways compared to the cinema from other countries but I watch most of these foreign movies with german dub. It is very rare that a movie does not have a German dub these days.
If a movie doesn't have a german dub I watch the english dub, I don't really care for original dub most of the time but if only subs are available I will watch movies with english or german sub.
the only exceptions are anime, I watch almost all of them with japanese sub and english or german sub, everyone who watches anime knows why.
German cinema peaked in the 60s with Winnetou. That shit was good.
