I just finished watching "Sword of Trust" and I give it above average marks as a movie. I thought it had good entertainment value, it had something to say without preaching it, it was well cast and well written. It was a low budget movie which used its resources wisely. And above all, it made no pretentions to be anything but what it was, and that puts it above average right there. I was not familiar with the works of Maron or Shelton prior to this movie, but I will look out for their names in future.
The story is simple and contains appropriate weirdness for this time in which it was made. Early on a pair of women receive an unexpected inheritance from the estate of an ancient relative: a Civil War sword that is argued to be "proof" that the South won the Civil War. I think writer even invented a new internet term, 'prover' (at least I had not heard it before). A pawnshop owner gets involved and the action mostly revolves around the interactions of the characters involved. I enjoyed Marc Maron's writing and acting, the writing was wryly humorous and observant. The acting was understated. I especially liked Jon Bass' performance as the internet junkie (barely) staffing the pawnshop. Michael Watkins and Jillian Bells' character interactions were believable to a point and well acted. Supporting character Toby Huss was properly 'over' acted and Dan Bakkedahl was solid.
I think it was well directed, well acted, the dialogue was cute and humorous for the most part. The background music went well with the rural/ semi-suburban ambiance of the picture, which I also liked.
Some of the action is improbable, but it is no more improbable than most movies, including high dollar high attendance shows that are not as entertaining.
This movie is about ordinary Americans in an age where the most ridiculous ideas are peddled to all and sundry allowing anybody to partake of any of a collosal amount of conspiracy theories including that the earth is flat.
If you like this movie at all you may be interested in a great audio album that predates the internet by a couple score years but does not predate the current insanity: Firesign Theatre's "Everything You Know is Wrong". It was consistently funny and way way ahead of its time. And still is.
