I think you just have to try to watch the movie without any specific expectations. I will go in there and make myself clear: "you're just watching someone tell Michael's story".
When I watched the musical I was totally hyped beforehand. While I was watching it, I didn't really feel anything. The show was spectacular, the dancers were on point, the story well told. And afterwards I asked myself why I couldn't REALLY enjoy it. And I think it's because I expected it to be an experience close to watching Michael perform. But it wasn't, his soul was missing.
And I think I would have enjoyed it more if I went in with a different mindset. (Like I said, the show was great, it was only my way of looking at it).
Also...it was German and that really took away from the experience, didn't even think of that 'til it started
