Personally it's one of the best TF shows put out in a while. Very good family values and personal lessons- like Jawbreaker worrying he won't be like everyone else if he can't find an altmode, and being told that he doesn't need to be like everyone else. He'll be who he is, when he's ready. The found family aspect of it is VERY sweet as well, and unlike anything I've ever seen in a Transformers cartoon.
The show is well written, well animated, and well designed- some older fans might be a bit put off by the redesigns of Optimus and Megatron, but their personalities will hopefully carry the older fans past that apprehension.
Earthspark also has the first main stream nonbinary character in the series- there have always been LGBTQ+ bots and cons in the comics, but the comics are a bit more obscure and mature. Not very suitable for children. Earthspark, however, is more than perfect for children and introduces the concept of nonbinary individuals very respectfully. Even including someone with "mismatching" pronouns (she/they) to go along with Nightshade's "they/them" pronouns.
All in all, it's easily in my top 3 shows in terms of story, characters, and values. Please give this show a chance if you're considering watching it.
