It's too bad that instead of HBO Westworld and Sony Dark Tower movie...there wasn't just HBO Dark Tower series with the quality and scope of Game of Thrones. It was a rumor forever. There are some similarities between Dark Tower and Westworld. A Dark Tower series would have been cheaper to produce because you could have as much as 40% take place in modern setting without much effects and still create an insane sci-fi/fantasy landscape. It may not be a coincidence if WW goes away from the wild west setting and more towards just 'slightly future' areas. The problem with Westworld is that it doesn't need to be a series unless there is some amazing new stories and characters underneath the premise. In terms of source material it isn't a proven packaged hit with a great market tested story the way GoT, Dark Tower, Harry Potter, LotR, or other hit book/comics long series properties are.
