Season 6 is quite a mixed bag of stories and not all of them are great but all in all it pulls together as quite a good year. The storyline once again takes a darker turn by letting the legendary character of Zod out to play though only by his spirit possessing Michael Rosenbaum's Lex Luthor and also the idea that super-villains manage to find their way to Earth and once again it's all Clark's fault. On the upside there is the introduction of Justin Hartley as Oliver Queen, a billionaire playboy who masquerades as Robin-Hood wannabe Green Arrow. The relationships again take centre-stage: Clark & Chloe's relationship gathers strength upon the revelation that Chloe may have a meteor-power but then receives a blow with the introduction of Jimmy Olsen as Chloe's love interest who spends most of his time embracing paranoia about Chloe & Clark's relationship, Clark & Lois continue their like/dislike relationship with this season providing a couple of real high points between the two: Hydro sees Lois recruit Clark to help her expose Oliver's dual-identity only for her accomplice to switch alliances and receive a kiss from his "frienemy" in front of their target; also Crimson sees the pair venture into a Red Kryptonite-enhanced romance which offers the viewer a glimpse of Clark freely using his powers to impress Lois and she freely accepting him. Lionel Luthor becomes an an Obi-Wan-like mentor to Clark while the Lex/Lana storyline is portrayed as though the writers couldn't be bothered, plumbed certain sci-fi B-movies for storylines but really wanted to continue flogging the - should have been long-dead - Clark/Lana romance horse. This series also sees the departure of much-loved Annette O'Toole as her character seeks advancement in the US Senate.
