‘Anything’s Possible’ marks Billy Porter’s directing debut with a teen trans love story

Marking Billy Porter’s film directing debut, “Anything’s Possible” is a sensitive high-school love story that’s so light on conflict as to risk blowing away. Placing a trans teen at its center adds some heft to material that would in an earlier era would have been presented as an after-school special, but the uplifting and timely messaging can’t completely elevate this earnest but thin Amazon movie.
