WATCH IN JAPANESE/FRENCH NOT 4KIDS!! Season 1 is alright, most of it is just fun stuff happening rather than actual story. Throughout the whole show, the music is really great though including tracks from the Adventure series (which is removed in the 4kids dub ofc). Then during S1 theres the adaptations of the Adventure games, which was great as well, then a couple episodes of "Eggman X" where half the moon being gone gets fixed but the show kind of hits a low here where only Sonic realises something that literally everyone else should've figured out first. And just after the "Natsu no Hi" scene at the end of S1, we get the Metarex arc for Season 2, where the show really picks up. Definitely worth watching, at least the last couple of episodes of S1 and the whole of S2. S2 is named S3 for the English dub, but you shouldn't be watching the dub anyway, because you will get a much worse experience with terrible music and censored scenes.
