Aubrey Plaza plays an over-achieving HS senior, who sets out to learn all about sex during the summer before college. If this sounds familiar, it’s been done many times with guys, so the unoriginal twist is girls! There’s every effort to be as verbally crude (sex talk) and visually gross (bodily fluids) as possible, but none of it’s very funny. Bill Hader provides the only true comic sensibility, while everyone else is just there (and about 10 years too old for their roles). The early 90s references are enjoyable, but so are a few noticeable anachronisms. There’s a good-spirited energy that keeps it from being too dull, but nothing about the writing or performances is especially original or amusing.
