First I had to make sure nobody else had tried this, because I hate being one of those people who attempts to be insightful but really retreads commonly held pop-cultural sentiments.[3] I fired up the ol Technorati, and I didn't find a straightforward Sleep v 'Smallville' comparison, but I found enough other entries to make me not want to try:
A running commentary (and an ironical use of the word "irregardless")
Screencaps galore (and an Erica Durance/Rita Hayworth comparison)
Iceman References (and different text from the TwoP site)
Pointing out that Philip Marlowe isn't Sam Spade (and the least text taken to spoil a plot ever)
Hair hangups (and synergy)
My favorite, however, has to be Smallville Guide's dueling reviews + transcript. That's love.
