What I thought of the movie "Wolverine: Logan"

At the beginning, when I saw Logan, pale faced, walk limped, drunk. I felt depressed. I remember how he used to be energetic before. Why the director arrange this? Until the professor be killed. I realized the era of the X-men has already passed. It's left with the look forward to and yearning of the movie fans. Even though this is the destiny of the humanity, I don't want to see this kind of end. I feel so sad.
