For non Sonic fans, this isn't going to blow you away, but it's a fun ride that's worth checking out.
Sonic fans will be relatively satisfied with how they handled the source material. Sonic is adorable and his old design just wouldn't have worked at all, so I give full credit to Paramount for listening to fan feedback and changing course. What the team did in just a few months is incredible.
The plot is what you would expect from a Hollywood adaptation, but I didn't expect them to fully dive into the lore. The human cast are good and there are quite a few laughs to be had.
Now for the bad: the film isn't to blame but rather the marketing. If you've seen all the trailers then you'll have seen the majority of the film. If you like what you see then do check it out, this film deserves to do well, especially so we can see what they do with the sequels.
