As a fan of the Sonic series, I can say with relief: "Well, at least they made a hedgehog normal." An alternative story about Sonic pleased, but did not reveal its full potential.
For example, rings, how without them? Open the portals and ... Stop! And is that all? .. Somehow it does not fit. Anyway.
Very few human emotions. If in the first half of the film everyone is scared of a hedgehog, then in the second half they react to it, as if there is nothing to be surprised at, but they look with suspicion.
I liked Dr. Robotnik as much as Sonic. For the first time in my life, Sonic, I began to empathize with the villain who, as an orphan, worked very hard to become a Megamind for the United States.
I can't say that the humor was good. Great emphasis is placed on Hedgehog, for which the film can be attributed more to the sweet, that to the humorous genre.
The rest of the movie was pretty good and very sweet. An exception to this is the relatively small budget of the film. I doubt that, within the framework of this budget, the director could make a film much better.
