Watchmen
Now, I think there were a couple of things working against me at the time I read it. One was the fact that I read it in the mid-90s rather than the mid-80s. By that time, various aspects of it had been frequently imitated in various ways, and what was revolutionary and groundbreaking about it no longer seemed so.
Laura has a story about being assigned Dashiell Hammett and Raymond Chandler in a college class, and complaining to the professor, "These guys write in such a clichéd style, it's driving me crazy!" To which her professor of course replied, "No, no, see, these guys invented this style. It was their thousands of imitators who turned it into a cliché." Well, I had a bit of the Hammett/Chandler effect going when I read Watchmen, even though intellectually I understood that Moore was the originator. His ideas just couldn't have the same impact on me that they would have had if I'd read them first.
My other disadvantage is the fact that the book is so highly and universally praised. Reading something after hearing bunches of people call it The Most Awesome Thing Ever I Mean Ever can hardly help but be a slightly disappointing experience. It's the expectation theory.
Well, having read quite a bit of the press around the movie and how it compares to the book, I think it's safe to say that I missed entire layers of that book in my first reading. I'd really love to reread the graphic novel, perhaps with some kind of Annotated Watchmen alongside it. (Okay Watchmen book, go stand over there in the line marked "to read." Yes, I know there are 112 books in the line. Hey, I pick randomly from the group, so maybe you'll get lucky.) Like the book, I think the movie benefits from repeated viewings. I know I was catching things this time around that completely passed me by on the first viewing. However, my overall opinion remains the same, which is that it is a very enjoyable superhero movie, with a great story, some excellent writing, magnificent visuals, and a couple of sublime performances, but it is also significantly flawed in certain ways.
