The art is of a good standard. The voice actors for the most part of pretty good, too. It really is pretty much just the writing that flaws this.
I didn't find it as bad as the outrage merchants have been saying. For example, when Teela flips out at the King and Queen when the news of He-man's death and true identity are revealed, her words are a response to the King just having exiled Man at Arms, her adoptive father for no fault of his own. And she does, seemingly believe that if she had known Adam was He-Man there might have been a different outcome (I'm not sure why). In any case, the criticism are valid but they do strip away little bits of context that make it not quite as bad as they sound. She's still a smug and bitter (weird combo) person for most of the run, though. Similarly, the bit about her deepest fear being how awesome she is, I actually don't think is too bad. They're clearly setting up the arc of her being the daughter of the Sorceress - or was it King Hiss? A hero afraid to embrace the power within them isn't that weird a story beat nor a bad one. The moral of "don't be afraid to stand out or be your best" is one some children need to hear. And He-Man is in it more than just the first episode. There are several flashbacks with him.
But yes, the criticisms are pretty much all valid and this IS the Teela show. It's not quite the woke dumpersterfire Nerdrotic and all that crew are portraying it as. It has good elements. Give He-Man back the sword, bring him back to life, it wouldn't be too bad. Smith needs to stop killing main characters, though.
