1) Every movie is a crap shoot. The only thing you can do to shift the odds is to start with proven material and hire proven cast and crew. Disney is doing that.
2) Hollywood in general is desperately trying to give you people exactly what you want as fast as they can, as well as they can.
You liked the superhero stuff? Here—have a dozen more. You didn't like Hulk? We'll MAKE IT OVER AGAIN. You like cerebral sci fi like Philip K Dick? Here's Inception, Looper, Total Recall, Chronicle, In Time, Source Code, The Adjustment Bureau, and whatever the fuck Charlie Kaufman does.
You're nostalgic for the '80s? How about remakes of everything that was popular only with big budgets? Plus, we'll keep the old franchises alive with new entries. You like books? We'll do all the Harry Potter, Twilight, Hunger Games... whatever sold over a million copies.
You want original stuff? WE GOT STUFF WE CAN'T EVEN EXPLAIN: Drive, Splice, The Fountain, Cloud Atlas, Cabin in the Woods, Abraham Lincoln as a vampire killer, joke trailers turned into action movies, military stroke jobs, martial arts movies with big budgets, cowboys and aliens together, remakes of successful European and Asian movies you didn't watch because you won't watch anything with subtitles.... YOU NAME IT.
ANYTHING and ANYBODY you like, we'll do more of that. And we'll hire directors who know what they're doing, and we'll give them big budgets and total control. You didn't like the Star Wars prequels? We'll pay billions for the franchise and give it to somebody who SEEMS to know what he's doing. WHAT MORE CAN YOU ASK FOR?!
I have my personal doubts about new Star Wars, but everybody seems to be trying make good movies these days, Battleship aside.
