Jimmy Olsen gets conked on the head while trying to deduce who shot Lana and dreams up a 1940 version of Metropolis where Lex is involved with lounge singer Lois and Clark is a cop undercover as a mousy reporter.
Linked to the larger arc of Lex creating a super soldier, this episode doesn't stand too well on its own. That said, I am excited to see how the season ends as always.
Pet peeve: The episode begins with Jimmy and Chloe on a date watching The Big Sleep, but in the end Chloe refers to Sam Spade. Was it too much trouble to make this a Marlowe reference and keep the continuity?
