Hey, “Edge of Seventeen” (2016). I saw what you did there. And you did it well. So I’m not going to spend the next 84 words belaboring comparisons to teen films from the 1980s. Suffice to say kids are different these days (and so are parents), but they still deserve good movies about themselves. And this is one. And a wink and a nod at the genre’s forebears signifies respect, not derivativeity. I’m also not going to continue discussing my non-sexual but age-inappropriate crush on Hailee Steinfeld, which began with “True Grit.” Suffice to say I’m glad she’s 20 now.
