Who liked it and who didn't?
Put me down as one who thought it was a bad movie. Not completely worthless, but there was a lot of bad dialogue and acting, it was too long, and it was gratuitously gruesome. And the characters felt flat to me, more there to deliver supposedly wry one-liners that came off corny too many times than to make me identify with and root for them.
Another thing that bothered me was the heavy and awkward use of baby-boomer classic songs. That has worked for films in the past, but the choices here were too over the top and I felt clubbed over the head with them. "All Along the Watchtower" (har har, get it, WATCHtower? forget it) and LC's "Hallelujah" became soundtracks to particularly irritating scenes.
No, I had not read it. I had started it and stopped.
