I think the writing is 'fine' per-say, but it feels disjointed, due to the development issues (the game's engine had a good healthy development time, but the problem is it feels the writing, while good on paper in theory, had to be hastily put together in the game itself, as reportedly the actual core development was within a year and it really shows).

Almost wish she'd done all the first year's worth of episodes, but we did get some good episodes out of it (the story about what happened on Arc, which the games never quite covered outside of the Japanese guides, the whole episode centering around Chris with Eggman's speech to him, and 51 in particular, analyzing Sonic and Chris's relationship at a much more deeper level and explaining why the two had the relationship they did, which, ironically, is the strongest aspect of Series 1 despite I know the fandom's general distaste for Chris).

I absolutely get that the first year (1 - 52) has serious issues, but the second series/season is really strong overall. Really, the whole Metarex arc of Sonic X has some of the strongest writing in the series, which was lead by Kiyoko Yoshimura, who also wrote several of the Sonic games (including Sonic Unleashed). The whole episode dealing with Molly on Episode 68, is probably one of the most disheartening and depressing stories in the franchise, given what happens throughout the episode, and what Molly ends up doing at the end of the episode in response. Sonic X during 53 through 78, honestly, while can be a little ridiculous, has some extremely sincere moments, really disturbing and difficult content that it covers, and actually treats it incredibly seriously.

Everything wrong with sonic generations
