I rated this one quite high and above current average. And this is because all that was intended here, was light heart escapist entertainment, no depth, no message beyond and above. Heinz Erhard was the German Comedian of a perfect kind, H.J. Kulenkampff the (later) lead Saturday Night Show Lead and Walter Giller, still very young, the light hearted bachelor. The story is easy, 3 guys of different kind get together on the Rhine, travel from South East Germany via Switzerland to Netherlands along beautiful landscape and with light intervention from the ladies, be they wives, possessive Girlfriend or surprised hands on freighter girl. Light Story, easy touch, well played --> going to 8.
