I agree with the list. Vaughn's films and the first two X are still great, but after The Days of the Future Past, I stopped watching any more sequels (with the exception of Logan.) They lost their charm and are just ridiculously simple and unattractive.

P.S.: Logan could've been a ballsy neo-western, which I expected, but I still appreciated the effort, the blood, and Jackman's and Stewart's goodbye to the franchise. (I watched Shane specifically before I went to the screening. It was a nice touch.)
