A snappy, scrappy, straining-at-the-leash coming-of-ager from bleakest Scotland, Brian Welsh’s “Beats” takes place in 1994 — two years before the release of “Trainspotting,” though 23 years on, it feels like something of an heir to Danny Boyle’s Nineties yardstick.
Human Traffic, sure, and a few scattered scenes in Trainspotting, the Berlin-set Victoria and the recent French drama BPM.
