I watched the 30+ minute cut found here: m.youtube.com/watch?v=n9zy-VQLL9I&feature=youtu.be
Since I didn't really watch the entire movie, I'm not going to give a rating. Even this portion is tough to evaluate since it has German audio. The subtitles and occasional title cards with text helped for context. You can get a sense what the actual movie is like -- not great, but not terrible either. It is quite depressing, as expected, but not to the extent that I would be embarrassed to release it if I were Lewis. It seems to rely far too much on voiceover narration so watching without might actually improve it.
