Reading Watchmen is, for me, akin to looking at the Mona Lisa. In my heart of hearts, I know it's a masterpiece, but I just don't like it. My main problem with Watchmen, and a problem I'm increasingly having with LOST (which I'm trying to catch up on), is that there's no hope for the characters. I have absolutely no reason to root for the characters in Watchmen; they're the saddest group of people in the world. The story is overly complex, the pacing erratic, and the tone is way too preachy for my liking.
I know lots of folks out there adore this story, but I say 'skip it.'
