When I first came across Saintia Shou and skimmed over the reviews, it gave me the impression of a half-baked show which people hated. However, as has unfortunately regularly been the case for many of the Saint Seiya shows after the original, the negative general trend of nostalgic reviewers have nothing to do with the actual quality of the show when seen with fresh eyes.
Saintia Shou is full bore Saint Seiya, with strong saints, key Saint Seiya elements and over-the-top melodrama wrapped in a classic feel. Sure, it has several shoujo elements such as petals flying around sometimes and magical girl elements but that's just a stylistic choice for this genre, the actual story is great and feels like Saint Seiya, only with a focus on female protagonists while much of the original show is happening in parallel.
Saint Seiya exists in a multiverse and this show's story is an alternate universe where much of the original show's events happen in parallel to the adventures of the Saintias however the new elements are where the main attraction lies. The show brings back Eris, a character from the first anime movie, expands her mythology and creates several interesting relations to follow as well as interesting world developments. The Gold Saints have a key role to play as well with the Bronze and Silver Saints crossing paths with the Saintias occasionally. Surprisingly, the Saint Seiya feel is preserved while working well with these characters as the female warriors are imbued with several of the characteristics usually associated with their male counterparts without taking away from their uniqueness.
Technically, the show is competently animated, the music is classic and great and the visuals are solid. Apparently the manga is much better (some of the negative reviews point that out) but without that baggage the anime is enjoyable and definitely got me interested in checking out the manga. The story also wraps up well and considering the manga is still ongoing changes to the scenario to achieve that are understandable (again, didn't read the manga when watching and enjoyed the anime).
TL;DR: This is a great and underrated show, watch it with an open mind and you'll have a lot of fun seeing what new things this story brings to the mythos while having strong female characters. It's a Saint Seiya show deserving of the name.
