A focus on relationship over objective plot results in a deficient narrative.
An emotionally exhausting film with two brilliant performances, Blue Valentine is a story not to be taken lightly. Unlike most films (though quite like many in its genre), the focus here is on the Relationship Throughline, the story between the Main and Influence Character. There is little to no Objective Story Throughline which, like the original Twilight novel, is why it probably won't find a very strong male audience. It's a shame, because in avoiding this film one misses out on witnessing a very real dissolution of a marriage.
