Great Movie! Worth getting tickets to! I loved the action and the build up to the big fight! Dr. Robot was very executed well in my opinion. I would say not end the movie with a cliffhanger ending credit scene, I will be sad if the next sonic villain isn't Jim Carrey, Knuckles in my opinion was cool, sometimes the CGI seemed off, I also think the ending could have been better because it always seems to happen to end with a happy ending, I think a better ending could be where sonic gets lost and can't find Green Hills and the next movie could be finding his way back but going through the other thing in the ending credits scene(Not Spoiling what happens in ending credits), On a final note, Great movie!
