It was ok.
(I’m not a huge Sega geek, so I can’t comment on the movie’s accuracy…)
I really hated the implication at the end of a possible sonic 4…. I don’t think we need another Sonic movie. There were points in the movie where it was easy to predict the lines. Shadow’s character arc was a little predictable. I will say though that I enjoyed the battle sequences between Sonic and Shadow, I thought the colours were really dynamic and engaging during fight scenes.
I did have some points in the movie where the special effects looked kinda iffy. Might just be me though.
Overall, it was an ok movie, didn’t hate it, didn’t like it either.
