I think I missed ever hearing about this one, maybe due to the lack of marketing you mentioned.
However, with the stellar @ezzy recommendation I think I might have to convince the wife to watch it with me. I think I saw it on our streaming service. After reading this I did check out the trailer and the sound track is filled with my type of jams!
It's a sweet movie, bro. and I'm sure one the wife will love too as even the violence is quite "tougue-in-cheek". But the jams certainly do play a huge part in making this movie as good as it is... :)
