This believably unhappy romantic comedy, about a 20-something couple falling apart, may mark the filmmaking debut of Chicagoan Dean Peterson, but it offers sharper dialogue and better performances than many a big studio rom-com. Susan Burke and Stephen Gurewitz ring true as the troubled couple, a successful law student and her disorganized artist boyfriend whose differences are sabotaging their life together. Also good are Alex Karpovsky as the oily seducer-next-door, Amy Seimetz and Alex Rennie as the couple’s “helpful” best friends, and Ron Lynch and Darlene Westgor as Burke’s dissatisfied parents. The movie should be funnier, but its last leave-taking scene is a beauty.
