Some might think "hey, b-list at best" but what they really mean is "b-list is best." It's cute and quirky and even though the main character can be a little bit annoying at times you really are rooting for her at the end. (Is that how you spell rooting?) The characters are, of course, on the shallow side, but that's kinda what makes them endearing. Plus it hints at some inner turmoil.
It follows the a-typical never would ever happen plotline of most movies of this genre but that's what makes it fun. It's kinda like a chocolate chip cookie--fantastically sweet pick-me-up with an aftertaste that makes you crave more. I'd watch it again. :)
