Was a little surprised by Ruby Sparks. Though it's directed by the duo that directed Little Miss Sunshine, it's actually the brainchild of the lead actress Zoe Kazan who has the title role of Ruby Sparks. Rounding out the 'Little Miss Sunshine' reunion is Paul Dano who also happens to be in a real life relationship with Kazan.
All of this familiarity is an advantage to both the filmmakers at the actors as the chemistry and relationship between Dano's character (a writer struggling with writer's block) and Ruby (a girlfriend that said writer starts writing about) is really fun and authentic. I know a lot of people aren't that fond of Dano, I don't hate him but I'm not a fan either, he probably turns in his best performance in this film which is why the relationship between his character Calvin and Ruby is so great to watch.
As the story progresses though, cracks appear which lead Calvin to reassess his life and who he is as a person. It's not a spoiler alert to say that Calvin eventually overcomes his writer's block, and it's the finishing of the story that makes it interesting.
