A summer-adventure comedy, and its tone is fairly synthetic, yet it gets major props for giving us the first movie heroine who is clueless and easy in such a hardcore way.

Making a convincingly assured feature debut, TV and web series writer-director Carey's script nails the raunchy-sweet tone required to bring off this R-rated teen-centered comedy with remarkable charm and relatability, mining a rich vein of girl-centered sexual curiosity and experimentation "loosely inspired" by personal experience.

Maybe someday there will be a better commercial comedy about a girl taking charge of her sexual education, but for now, this is the only one we’ve got, and it’s a filthy-fun charmer.

So many “lose my virginity over the summer” comedies, from “American Pie” to “Superbad,” “Can’t Hardly Wait” to “Girl Next Door.” But aside from the hilarious “Twilight Saga,” how many have told that torrid tale from the girl’s point of view? The To Do List is a summer romantic comedy dedicated to rectifying that imbalance in a single stroke.

What really sets this film apart from nearly every other teenage sex comedy ever made, from "Porky's" to "American Pie" to "Superbad," is that this isn't about some dude trying to get laid.
