What I liked
-Jim Carrey is the goat. He does a different take on Robotnik and yet it fit. A nice combination of the jokester Robotnik and the serious one. Fans of all incarnations should be able to find a little bit of what they like.
-Ben is arguably the best Sonic ever. His voice and personality is what I imagine when I think of Sonic especially with Sonic
. His personality also fit as an origin point. I could see Sonic acting like this before he decides to be a hero.
-The movie was entertaining all the way through and actually keeps interest when Sonic is not fighting Robotnik or when the human characters are on. People that watched Sonic X know humans can kill a Sonic story.
-The changes to the origins were fine and that actually not only fit the plot but open up ways for sequels to go.
-I felt like I could go play Sonic 1 after this film and it would fit which was nice.
What I didn't like
-I could have done without the small change to Sonic's power but it is what it is. I also thought the change to the rings could have been better but these are just nitpics.
