See? This is exactly what i mean, this passive-aggresive style of comments.
The X-Men are with Marvel already, but under fox, the mcu has not handled very well anything, disney knows how to make business with them, not how to handle them.
Overall yeah the mcu is okay and unique but it also has plenty of flaws, a lot of underdeveloped and rushed stuff (what they did with SHIELD in the movies is a good example, the Captain America trilogy is a good example, Thor Ragnarok is a shining example of disney completely not kowing how to handle a character) and etc.
In case you did not noticed, all superhero heroes movies try to be "grounded" no matter how many fantasy or science fiction elements are in it, so your point does not make much sense. And is not focused on Wolverine, and they do not wear black leather all the time...
And is not the "end of the story" yet, we have one more awesome X-Men movie coming, no matter if you want it or not
Also, while being pretty bad, ASM2 has several good moments.
Homecoming has one, and is brief, everything else was not handled well at all.
