I'm not remotely qualified to discuss this aspect of the film, but I felt it would be irresponsible for me to talk about the strengths of the rest of the film without mentioning it.
I love Yasiin Bey as an actor, and his character in this movie is great.
I'm avoiding spoilers as I discuss the movie because it's new enough and obscure enough that chances are good that not everyone who might want to see it will have seen it already.
It isn't actually new or obscure, but still.
This movie introduced an idea, though:
"To Swede" - The process of remaking a commercial film without a commercial budget or professional actors. The resulting film is a "sweded" film.
The etymology for this turn of phrase within the film aren't important to the rest of this discussion, but "Sweded" is useful shorthand for a specific visual style and concept that I want to discuss at length.
The movie stars Yasiin Bey (aka Mos Def), Jack Black, Danny Glover, and a bunch of other people.
It's about a video rental store in a poor neighborhood in NJ that is condemned and going to be demolished. The store sells VHS tapes and is not financially successful.
This provides the set dressing for a film in which a community gets together and makes movies, including a fictional biopic about Fats Waller.
A community producing it's own media is Very Much my shit, and the movie is good.
