Spoiler alert...
I'd say it's a cool movie. When the trailer came out I was so excited. As expected shadow was a cool character they made him look awesome. especially the scene where sonic and shadow uses the chaos emeralds and the fight scenes looks cool. However... it's not a perfect film and it has some flaws that I'll point out. I think the main issue i have about the movie Is that Gerald and eggman had way too much screen time trying to be silly and comedic as possible and I never really laughed at any of the scenes. I think the movie should've spared SOME of the screen time for either shadow or sonic and his team. I was expecting Tom to join gun which that would've been awesome. I absolutely loved the end credits scene I was happy when they showed metal sonic and Amy rose. Overall great movie I just wish they didn't do too much with Gerald and eggman's bonding scenes.
