This is darn near impossible to review without spoiling, but challenges are fun. So, on it's surface, SSSS.Gridman is a giant robot vs kaiju of the week show. The combat scenes are done in a manner that accurately depicts what a fight like this would look like if you were filming men in rubber suits, and this was done for a very specific reason.
The villain in this show is my choice for villain of the year. They are deeply layered and interesting. The remaining cast, at least at first was really two dimensional at first. Gorgeous best friend next door. Nerdy buddy. Generic love interest for the villain. This, once again, was done for a very specific reason. However down the road, some of the rest of the cast grow into much deeper characters.
The setting of the show, is beautiful in it's emptiness and kaiju clouds in the background, which was done for a very specific reason.
Look, SSSS.Gridman on it's surface is a fun giant monster/mecha anime, but there is a lot going on under the surface here. This takes a fun show, and elevates it to brilliance. For you to totally know why, you'll have to give it a watch. Trust me, you will not be disappointed.
P.S. If you're still mad at Trigger for the end of Darling and the Franxx, they redeem themselves here.
Now go watch this show!
