The Taylor-Johnsons have made a well-meaning version of a story about addiction, but given what we know about James Frey, A Million Little Pieces doesn't feel like enough.

As a stand-alone work of cinema fiction, "A Million Little Pieces" is an effective blunt instrument of a film - a rough-edged, unvarnished, painfully accurate portrayal of addiction and rehabilitation.

A petulant, boastful, and not very noteworthy variation of a story that plenty of films, documentary and fiction, have told before, but with more insight or panache.

Pieces ends up diluted, yet another trip to rehab and redemption, with some encouraging words from a therapist on the way; it will not remind anyone why this weird saga unfolded in the first place.
