I read Watchmen when it first came out, and although I enjoyed it, it was a long time ago. So my recollection was hazy.
Anyhow, the credits were awesome. But by the time we were learning about The Joker's past it seemed a bit po-faced and, yes, over-stylized. I fell asleep, having had a long day, and woke up long after it finished. I will get round to watching it and doing it justice another time, it looked very promising but perhaps too demanding for late on a Saturday night.
