Picking up where its fifth season left off,Smallville's sixth season begins with Metropolis in ruins, Clark (Tom Welling) trapped in the Phantom Zone, and General Zod inhabiting the body of Lex (Michael Rosenbaum). Even when that situation, dubbed "Black Thursday," is over, Clark still has to capture the criminals who escaped from the Phantom Zone. Meanwhile, having driven away Lana (Kristin Kreuk), she finds comfort in the home and arms of Lex, driving further anxiety into that romantic triangle that has expanded to include Chloe (Allison Mack, still with a smile that lights up the orb on top of the Daily Planet) and her new beau, photographer Jimmy Olsen (Aaron Ashmore). And Lois (Erica Durance)?  We see hints of her inevitable future in her becoming a reporter for the tabloid ragThe Inquisitor("The thrill of discovery, the clack of the keys, the scent of fresh ink… I think I've finally found my calling!") and flashing some sparks with Clark especially in a Valentine's Day episode called "Crimson."She also finds a new boyfriend in Oliver Queen (Justin Hartley), a tycoon who moves from Star City to Metropolis and revives a boarding-school rivalry with Lex. But Queen is also a superhero, the Green Arrow, and he's out to thwart Lex's project called 33.1, which runs tests on meteor-powered humans. And in an awesome episode called "Justice," the Green Arrow gathers his team--Bart Allen (Kyle Gallner), a.k.a. Impulse (a change after he was first called the Flash); Arthur "AC" Curry (Alan Ritchson), a.k.a. Aquaman; and Victor Stone (Lee Thompson Young), a.k.a. Cyborg (who had all appeared in the series before)--with Clark to shut down Lex. Yet another hero from the comic books--an interplanetary detective (Phil Morris)--helps Clark fight rogue Kryptonians. It all ends in a slam-bang finale with a number of surprises.  Even though the Lana drama went on too long, Green Arrow and some choice episodes stuff made this one ofSmallville's best seasons. Guest stars include Tori Spelling as a nosy gossip reporter and Lynda "Wonder Woman" Carter as Chloe's mom.--David Horiuchi
