I watched Detective Pikachu as well (But I'm a fan of this franchise - not a big fan, but a fan nonetheless)
It was very cute and I liked it. But I didn't love it. What rating would you give it, out of ten?
I think I would give it a 6 or something like this. Simply because I agree with the things you mentioned in your comment.
I watched a few more movies lately:
Avengers: Endgame 10/10 - no explanation needed. I love the MCU franchise.
Million Dollar Baby: 10/10 - I like Hilary Swank and the story was good without getting overly-dramatic
Mary Poppins returns: 9/10 - I like the songs and Emily Blunt but the story was lacking occasionally.
