I just watch the Princess of Mars SYFY channel movie based on the ERB books, I have to say it was good, I felt like it stuck close to the source about John Carter. It had Dejah Thoris, Tars, and it even had an airship, all in all not to bad for a SyFY channel movie. The Tharks looked good and it even had Sola in it as well! I downloaded the first five ERB books to my nook. Finished book one and now am on to book two.
