Last week a new trailer for Disney's "John Carter of Mars" was released. It definitely looks better than the original teaser I posted. I still have reservations about how it appears they've reworked Dejah Thoris into "D&D Warrior Babe" and tinkered with the plot (what on earth was that lightening disintegration gun supposed to be -- I don't remember that), but I was glad to see many of the most memorable scenes from the books pictured in the trailer (such as Dejah Thoris' almost-wedding to Sab Than, the evil prince of Zodanga, the meeting of Woola, leading the Tharks against Zodanga)
So now I think I probably will see it, perhaps even in the theatre. But I shall try to keep my expectations low!
