If you follow me on my SFW account, you'll know that I saw the Sonic movie not long ago and loved it.
I went in cautiously optimistic and came out of it loving everything that I saw. I really liked the new design and the overall aesthetic of the movie. The story was even charming and I was touched at the climax of the film.
Do I recommend it? Absolutely, I do. If you're a Sonic fan, you'll be in love. If you're a casual fan, you might find it cliche and underwhelming in the story department with some pacing issues. If you hate Sonic, don't bother watching it.
