Tonight we went to see John Carter and really enjoyed it. It was the sort of fun, sprawling fantasy epic that you enjoy as a kid. The visual effects were a delight without being overwhelming. The story introduced just enough mysterious mythology to intrique you withous mystifying or confusing you (and fortunately they didn't spend a lot of time trying to explain things). The supporting characters were enjoyable.
I have never read the books, but will put them on my list. It is easy to see how this story influenced later science fiction and fantasy. It seemed to have a few Wangerian influences on it.
Go for the fun of it.
