All hail the Green Arrow! The arrival of the Emerald Archer (Justin Hartley, star of the failed Aquaman spin-off) expands the scope, action and cheesy fun of Smallville’s latest run. The Archer’s arc peaks with episode ‘Justice’, which sees a nascent Justice League – Aquaman, Cyborg, The Flash and our Teen Of Steel Clark Kent (Tom Welling) – banding together to thwart Lex Luthor’s genetic dabblings. Even Lana Lang gets a beefier plotline, thanks to her anguished nuptials to Lex. Lob in a cheeky new Jimmy Olsen (Aaron Ashmore, bro of X-Man Shawn) and you have young Supes’ best season since year two.
