I’m a lukewarm watching of Smallville. I used to watch it when it was brand new, got tired of the Lana obsession of Clarks, and the unlikelihood of Chloe/Lex actually happening, but turned in to Absolute Justice for Michael Shanks, and was brought back to the fold by Justin Hartley as Oliver Queen (and his chemistry with Alison Mack as Chloe). This is my first season watching it again where I start at the beginning
(a very good place to start).
Spoilers beneath cut.
