For a movie that pipes in Carly Rae Jepsen and Taylor Swift to pander to the kids of two a long time in the past, this is a weirdly refined and intriguing option. Landing someplace among Once and Begin Again tonally, Sing Street is a soppy sweet really like letter to the Dublin of the 80’s packed with childlike joy and surprise, a gaggle of Spielbergian kids you just want to hug, and a heap of marvelous fake New Wave jams.
