Despite the incredibly poor taste of making comic hay out of Johnny Cash's brother's tragic, way-too-early, and doubtless traumatic death, this is an often hilarious mock riff on biopics and the music industry in general,...Cash rules everything around him (Spin magazine),
Silly and hilariously goofy. It's a guilty pleasure but worth checking out for the plethora of cameos, gags, and laugh out loud moments. It drags on, is prepubescent, and gets annoying, but that's also it's charm. It seems like everyone involved is having a blast. John C. Reilly is killer and deserves a lot of credit for keeping this from falling apart.
