SPOILERS WITHIN.
It appears that von Trotta was a lot more at ease with what the balance of personal story versus history of the events than she was in her earlier film Versprechen, Das (1995).
The direction seemed carefully controlled, and visually I felt it was highly appealing - especially where the visual narrative was concerned (the title-sequence blend and the lighting of a new candle in modern times commemorating the deaths of various characters in the past).
To clarify two points that many people have been confused by:
Firstly, Lena did not sleep with Goebbels. Although this may have seemed implied, it was not the intent. Von Trotta told me so herself! (And she is a very nice lady, by the way!)
Secondly, the time-frame of events was in fact historically accurate (the actual dates are shown on the close-up of the memorial) and the prisoners were released as suddenly as in the film. There is evidence showing that Goebbels was annoyed about having done this, and had planned to eventually recapture those he had set free.
Overall, what most impressed me most was that it was an original story from a much 'over-movied' era. It seems a shame that it has taken such a long time (for various reasons) for this film to hit our screens.
More of the same please, Margarethe!

Before Stan Laurel became the smaller half of the all-time greatest comedy team, he laboured under contract to Broncho Billy Anderson in a series of cheapies, many of which were parodies of major Hollywood features. Following a dispute with Anderson, Laurel continued the informal series of parodies at Joe Rock's smaller (and more indigent) production company.
Most of Laurel's parody films were only mildly funny at the time, and even less funny for modern audiences who haven't seen the original movie which Laurel is parodying. 'West of Hot Dog' is a fairly generic parody of cowboy shoot-'em-ups. It's marginally a specific parody of 'West of the Pecos', an oater released two years earlier with no major actors. Since 'West of the Pecos' was never a huge success, it's difficult to see why Stan's film unit chose this particular movie as a target for their lampoonery, much less why they waited so long after its release to parody it. And where did they get that title 'West of Hot Dog'? Possibly it's down to the fact that 'Hot dog!' was a sexual interjection favoured by American lechers in the 1920s. (As in the opening scene of the stage play 'Machinal'.)
'West of Hot Dog' was produced and co-directed by Joe Rock. Among his many other achievements, Rock introduced Laurel to Lois Neilson, and he was subsequently best man at their wedding. Full disclosure: In the last years of his life, I had the great privilege of befriending Joe Rock and interviewing him. Nearly ninety years old at the time, Rock's memory was impressively clear ... but he remembered nothing at all about 'West of Hot Dog', and I can't blame him. This movie is eminently forgettable.
The leading lady's character is named Little Mustard: If that's meant to be a parody of something in 'West of the Pecos', I don't get it. There are a couple of 'impossible' gags here, including Laurel's method for mounting a horse. For just one moment in this movie, Stan Laurel reminded me of the great Buster Keaton when he suddenly broke into a run. 'West of Hot Dog' is vaguely similar in subject matter and tone to Keaton's short comedy 'The Frozen North', but Keaton's version is much funnier. The plot of this film somewhat anticipates a situation in Keaton's feature 'Our Hospitality' but (again) suffers by comparison: here, two tough varmint brothers expect to inherit the Last Chance Saloon, but the previous owner has bequeathed it to weakling tenderfoot Stan. However, the brothers will become the legal heirs if Stan dies. Hmmm...
Seriously, though: is such a bequest legal? As soon as Stan takes possession of the property, surely any further questions of ownership or inheritance become his decision, not the previous owner's decision. I had plenty of time to consider such points of law while watching this dull comedy.
At one point, a gag involves some crude animation drawn directly onto the film stock. It looks cheap and isn't funny.
This 'Hot Dog' is no weiner, and no winner: it's just a whiner. My rating: one point out of 10. Hang on, Stan: in a few more years you'll be one-half of a comedy legend.
