The director seems to take his cues from Zach Braff (Garden State), with the Scrubs-like frame skips and indie-emo tracks; though he lacks the sense of artful timing to pull this off effectively as a tool to convey any sort of depth beyond merely getting characters from one scene to the next.
Son of Morning seems to be more of an experiment in the use of frenzied background music to convey the emotions normally exuded in film through writing and performances. It overshadows nearly every potentially-interesting scene with a hasty mix of tracks and sound effects layered on top of one another. It (probably) wants to convey the confusion and/or hysteria of an ordinary kid suddenly being catapulted on a wild ride through pain/tragedy/stardom, just in case the audience doesn't get the point via the pedestrian performances.
If indeed an experiment, it's a failed one, as the music is purely a distraction. A big distraction that is the final nail in a coffin already firmly glued shut.
More mess is amply provided by the parade of uninteresting performances (aside from Danny Glover, the only person worth watching in this cluster-bleep), missed opportunities, awkward pauses, and other missteps. It's a rambling collage with little idea of what it wants to be, and feels long despite being a relatively short film. It eventually attempts to spell out some message that doesn't seem terribly relevant to the brunt of what came before. Overall I found this to be a rather annoying movie.
