Finally! After a few mediocre episodes, Justified finally pulls a rabbit out the old Stetson with “Weight.” This episode is jam-packed with twists, turns, and eye-popping surprises I didn’t see coming. From an old friend (or enemy, depending on who you are) wheeling into a family feud that’s been brewing since the beginning, “Weight” holds no punches in the violence department. Will these surprises be another anchor weighing Justified down or the invigoration it needs? Either way, I’m along for the ride.
