I think with Dark Tower, WB wasn't sure what to do. Remember their plan was to do the movie (set in a cycle after the book series) and then a prequel series (about a younger Roland from a cycle before the book series). I think they needed to be thinking more about plot than their long term media plans...
MCU has made Thor a comedy relief, which is strange because he never really was in the comics or any of the cartoons... well unless we're talking about Throg (Frog version of Thor). MCU has pretty much given Thor the "All brawns, no brain" element which makes him not unlike Hercules or Conan The Barbarian. I guess it makes sense that they would do that on the screen though, it seems to tranlate well.
I can't wait for Black Panther. I only hope they introdce some more hero movies (with different heroes).
But yes, Marvel movies squash the DC movies... the same can't be said for the tv shows. Marvel tv shows aren't doing so well while DC tv series such as Smallville, Arrow, etc remain top rated. Strange but that's just the way things work I guess.
The director said he was influenced heavily by BIG TROUBLE IN LITTLE CHINA and saw Thor as kind of a Jack Burton character. I can see it in the way they presented him. He's not dumb, but he's also clearly not the smartest person either. And his ego gets in the way, but he has a good heart and a lot of determination.
About 109 minutes, according to IMDB.
