Although I am not a big fan of his movies in general, this interview is very interesting, hilarious and worth to watch. Personally, I enjoyed it very much. They even had to censor a part where Uwe talked about Michael Bay because Bay threatened to sue (lol).
The petition to stop Dr. Boll from making movies is also mentioned.

Here is a good review (taken from the blog):

Better than all of Boll’s films combined
I watched this documentary not because I am a fan of Uwe Boll but because I really enjoyed the previous work of host and director Fabian Hübner (have a look at my review for avant*garde). The big advantage of “Visting Uwe” is that one doesn’t need to be an admirer of Uwe Boll and his films in order to enjoy it. In contrary to most of the interviews with Boll, this one doesn’t want to exploit the controversy surrounding his person but tries to reflect his points of view on film, art and creativity.
The concept to talk with a widely detested mainstream director like Boll about Art-house, Godard, Tarkovsky or Lars von Trier is hilarious. One might think that “king of trash” can’t cope with such a “difficult” topic but that is not the case. I was surprised to see that Boll has serious knowledge in the field of film. He definitely knows what he is talking about. The fact that Hübner is equally trained makes the whole interview even more interesting and entertaining.

In the end “Visiting Uwe” is by no means your usual boring interview. It’s an entertaining and at the same time informative discussion between two film enthusiast, which is accompanied by a visually fresh style and wild punk rock music. If you want to learn about art-house films without falling asleep and at the same get an in-depth view in the mind of Uwe Boll, this is your place to start.
