I can't enjoy movies/series anymore. Any help?

Don't get me wrong, I love cinematography. as a little boy, I used to watch movies from the video store every weekend with my dad. I have spent thousands and thousands of hours watching movies. Even though my dad is gone, I still carry my love for movies and even taught it my girlfriend.

Unfortunately, I stopped enjoying movies/series lately. I can't keep the attention of the story, the characters don't interest me, and I feel like I'm zoning out during it. When I watch the series, I can't get past the second season. I feel that I have already seen the best and that there will be nothing better.

Everything seems so tasteless to me, despite the fact that it is well filmed.

I miss those emotions...

Is there anyone who has the same thing?
