Marwencol

Marwencol was an interesting documentary to say the least.  My favorite thing about the documentary is the way it was shot.  It was very unconventional as in it wasn't the standard talking head with B roll type documentary.  The talking heads were very natural and informal and the bulk of the interview coverage was in the b roll.  I feel this really fit the character of the story they were trying to tell.  I feel a formal documentary would have taken away from the story.

Best Worst Movie

Best Worst Movie is a fantastic documentary.  It tells the story of the cast of Troll 2, widely considered to be the worst movie ever made,  and how the movie has affected their lives.
Much of the film is lighthearted or humorous and you have a ton of fun watching it but then there are several moments that can't be described as anything but awkward.  The director of Troll 2 believes that he did a good job and thinks that the rise in its popularity is due to people finally realizing it's genius.  It almost makes you cringe as he discovers the real reason people love the film and tries to defend it as the rest of the cast and crew tear the movie apart.  Probably the hardest part to watch is when they visit the actress who plays the mother in the film, Margo Prey.  She is delusional and thinks that the movie is comparable to Casablanca.
All in all this documentary is worth a watch and might even be worth owning.
