I guess it's just a matter of taste, and there's no point in reiterating my reaction, BUT...

I response to LH, let me just defend my position my pointing out that I never had a problem with the original film about Hitler that was used as the basis for this, er, parody (or whatever it is). What leaves me cold is the attempted humor of the adaptation (or whatever) created by adding captions to the original film.

And I certainly don't take the position that Hitler was only an "ill-termpered windbag." He was all that and more, of course ~ although, in the context of this portrayal of him as a person losing his grip over the choice of entertainment at his birthday party, I though it might be safe to omit discussion of his more serious failings.
