This show has been like a breath of fresh air for the Isekai genre. The art is beautiful, the story is fairly well written, and it's fairly straightforward (i.e. not a convoluted mess of a premise like other Isekai out there). If you're looking for a more relaxed 'summoned to a new world' type of anime, this is definitely for you.
DETAILS:
The real beauty of this show comes in the form of its character-driven focus. Don't come into this show looking for action - the show is very low on that so far. However, the way the show looks at the struggles of its main character (and even some of the side characters!) is its main selling point. You really feel the surprise, shock, and other dilemmas of Sei and the supporting cast. One episode goes out of its way to focus on the internal struggle of a side character just to add context and realize that the show's conflict is much more nuanced than you would expect at face value.
The art is gorgeous! The colors are bright and well defined, not falling into the modern Isekai trap of muting many of its colors.
The story is slow paced, and I could see why that would annoy some. However, I like the pacing - it allows for more character development and world building (which the show does a decent job of, as well). Another modern Isekai trap avoided here - a lot of modern shows make their plots rather complicated to differentiate them from others in the Isekai genre, but The Saint's Magic Power is Omnipotent doesn't need to do that. The story is simple and streamlined but still well-paced enough that it can focus on the characters and their struggles in order to further progress the plot.
Another small nitpick is that I've noticed that the subs don't always match what the characters are saying. The meaning has been changed ever so slightly either to streamline something or provide more context.
CONCLUSION:
The Saint's Magic Power is Omnipotent gracefully dodges the pitfalls of many modern Isekai shows to provide more of a fresh take within the genre. All in all, this is definitely a show worth checking out!
