Louis Theroux: The Most Hated Family In America (2007, Geoffrey O'Connor)

The documentary is about an extremist church in America that preaches the message that homosexuality is wrong and is against the bible and god. Moreover they target innocent targets such as soldiers that fought for America in the war and picket their funerals. 

The documentary is interesting as throughout you are introduced to a multitude of characters that are all different and the main character that leeds Louis around makes the storyline complete.
Louis Theroux stars as main feature character in the film and is very directly involved with many aspects of the family through going to their pickets and experiencing day to day life with the family.
The main characters from the other side of the camera include Fred Phelps as the leader of the church although we don't see much of him he is a main character. Shirley Phelps directly leads Louis around the church and homestead and is the main consulter and come to person to answer questions.

There is diegetic and non diegetic sound throughout that makes the documentary interesting and gives some meaning and understanding behind it.
The sound in the documentary is optimised and used well to at times create the atmosphere that the viewer wants to see.

Louis' interviewing style is very direct and this comes across in the film although over the place at times his questioning is direct and to the point and he gets the most information he can out of Shirley and her church members moreover he can outsmart the church members to get a greater response.
