Thank GOD that Disney doesn't have the X-Men!

They're not original concepts, they are all based/inspired by comics produced by Marvel/Disney, so if you're going to give the finger to Disney you might as well give the finger to the films you list as they would not exist without Marvel creating the books that gave them life originally. 

You also seem to think that listed films are the norm for the franchise when they really seem like tiny patches of light instead of a shining star. As a whole the franchise is pretty uneven, when things are good they're very good but if they're bad they're very, very bad - X-Men Origins: Wolverine might as well be their equivalent to Batman & Robin seeing as they erased it from existence after it came out and was met with so much heat.

Marvel and Disney are also happy for the success of Logan and Deadpool and what the other better X-Men films have accomplished, this includes the filmmakers like James Gunn and Scott Derrickson.
