DVD: Law-Abiding Citizen, For retail & rental

When Gerard Butler's wife and daughter are murdered, he vows revenge, not just on the killers, and not just on the prosecutor (Jamie Foxx) who plea-bargained on their behalf, but on the whole of Philadelphia's legal system.

So is it a vigilante thriller, featuring a bereaved everyman with a righteous cause? Or is it a far-fetched, Seven-style shocker about a mad-genius serial killer? Law Abiding Citizen tries to be two kinds of exploitation film at once, and it ends up as neither.
