A nerdy grocery store detective begins "sexual training" to earn the affections of a musician.
Cristin Milioti, aka the girl with the yellow umbrella, shines in the lead role, but the film is troubled by the fact that very few of the characters are at all likable. Normally, unlikeable characters aren't a problem for me, but when the object of the protagonist's affections is an utter dick, we judge the protagonist; we all put on our "gay best friend" hats and say, "Girl, you're so much better than this."
Some of the situations Sammy finds herself in are chuckle-worthy (the mother teaching Sammy how to use a vibrator and the resulting threesome), but that's about the extent of the film's humor.
Overall, Ted's future wife is quirky and adorable, but her film choice needs improvement.
