I have a girl crush on Jennifer Westfeldt (which seems appropriate for this movie about a buttoned-up Jewess trying on lesbianism to find her  true love[s]). Too bad she's all in a committed long-term relationship with hunk-o-man Jon Hamm.
Westfeldt as Jessica is so adorably neurotic and girl-next-door-pretty. My perennial favorite, Scott Cohen, is mean and tough but also sweetly anguished. Jessica and Helen's romance blossoms awkwardly and hilariously at first, but the moment Jessica comes over to take care of Helen when she's sick is a nice turning point. The movie debates homosexual politics a bit, but it doesn't end with a clear message about whether one should be with her own sex or the other. It also doesn't cheapen Jessica's lesbian relationship as a dalliance.
I also love how the script sneaks in bunches of word-nerd humor and suffering artist philosophy. Judy's monologue about how Jessica quitting the school play because she thought her costar wasn't good enough - and only really hurting herself - is a metaphor for her dating life is eloquent and insightful. Josh's realization at his happiness for Jessica's painting and his own novel writing is a necessary reminder for all creative artists. Blech.
