Maxed-out credit card! What's a girl to do? This week, Isla Fisher faces that age-old dilemma in 2009's powerful exploration of retail existentialism, Confessions of Shopaholic -- from director P.J. Hogan (My Best Friend's Wedding), the man often cited as the Tarkovsky of rom-coms. Another poignant social treatise arrives on DVD this week in the form of fat-joke auteur Kevin James' Paul Blart: Mall Cop, an elegant reverie on the economic plight of the working class subversively disguised as a series of cheap-seats pratfalls.
