Funny in that “heh-heh” way, and very well done by everyone. I particularly enjoyed the songs and obvious setting of place and age via character dialogue a la: “You are the best 14 year old son I could ever ask for.” The DVD extras include a funny feature wherein actual famous musicians pretend Dewy Cox is real.
ps. Dan Bern is a songwriter on some of the songs and there are also THREE actors from The Office in this movie.
