I know for a fact a lot of people did not like this show. Now just ignore those negative reviews. I know this show has some cheesy moments, and if you don't have a high cheese tolerance and expect this show to be like the action packed games, then just skip this show and watch a different one.
Now that we got that out of the way, here's my review of the show:
The plots of the show are similar to those of normal CN shows like Teen Titans Go, and The Amazing World of Gumball. I think Teen Titans Go is lousy, annoying, and so boring that it makes me sometimes change channels. Also, The Amazing World of Gumball is mean spirited, cruel, and boring, topped off with unlikeable characters. That said, why do I give it such a high rating? Well, although the plots are so simple and frankly weak, it does it in a way that it is actual funny and entertaining, and not boring. In fact, it is sometimes deliberately dumb, making it funny and entertaining. For example, one episode is about a music star named Justin Beaver who brainwashes girls like Amy and Sticks for an evil plot. The most criticized part about this is what they did with of the old characters. But I actually find them very amusing and a lot of fun, especially Dr. Eggman, who is my favorite character for being both funny and likable. Also, although Knuckles has been changed to arrogant and stupid, he is actually still a likable character. But there are some things that bring the show down. Like the animation is pretty good, but the lip sync is bad. However, at least this animation is better than the abysmal cut scenes animation and graphics in the Sonic Boom: Rise of lyric video game. Also, while the voice acting is pretty good, with Mike Pallock doing well as Eggman, Roger Craig Smith as a pretty good, but whiny sounding Sonic, but some voices like Tails and some of the other villagers can be a little annoying. Also, some episodes such as the 4th episode, Buster, are not good at all.
So overall, Sonic Boom is a good cartoon, so much better than some of the shows we have on there today. So if you do have a high cheese tolerance, than I recommend it. If you do not, I would recommend giving it a skip. 7.5/10
