I saw six films at Tribeca this weekend, and five of them were completely blown off the map by Somers Town, Shane Meadows’ practically perfect follow-up to his 2007 triumph, This is England. England was one of my favorite films of last year, but its political/historical aims, admittedly, occasionally overwhelmed Meadows’ more subtle, character-based observations. Somers Town is less ambitious but more impressive, a 70-minute portrait of a moment with zero fat to cut and not a false note.
