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