The idea of the result is quite nice, but in the implementation rather weak. Aunt Paula is represented as totally dependent and incapable of short full Depp. In episode 23, she was still a tough business woman (or wife of the bank manager and sent) and negotiated properly with the Count. At that time she was just a little clumsy when it came to riding and horses. Otherwise she was resolute and sympathetic. Here she goes Bibi and Tina from the very beginning on the nerves. You can look forward not about the visit, although it has both time yet so helped. I think her performance in any case terrible. And nerves the constant mentions of their characteristics (references to their first appearance). Had the authors let them convincing appearance, the listener would they be able to assess themselves and they should not be described ("You know, if I want help, I'll help." Or "Have you forgotten ...").
I was looking forward to a good-bye to Aunt Paula and was disappointed. Another time can be dispensed quietly on this character, at least if he is represented. Who does not need the result to complete his collection, it does not necessarily have.
