The main character of the anime is Yuuta Hibiki - a high school boy that wakes up at Rikka Takarada's home having no memories at all. At the Junk Shop, which belongs to Rikka's family, there's an old computer called Junk. And inside of it there's Gridman - the Hyper Agent telling Yuuta there's a mission he needs to fulfill. Yuuta lets his school friend Utsumi in on what's happened and when huge monsters called kaijuu start attacking the city, these three form the Gridman Alliance and with the help of the robot inside Junk, they start fighting said monsters and begin the journey to discover the truth about the city and everyone in it.
Since the very beginning there's a feeling that there's more to the show than it might appear at first. In what could be labelled as a naive show targetting the younger audience there's always the feeling that something is off and with every episode the eerie atmosphere becomes more apparent, which only makes the experience better. I loved the mysterious atmosphere of the weird, closed off city and the scenery filled with giant dormant monsters reminding you that even the calm days aren't how they should be.
What adds to the atmosphere is the background music, or rather the frequent lack thereof. Because of that (and of the animation) some scenes look pretty slow, but I wouldn't call it a bad thing in this particular case. The music does always appear during the fight scenes, though, and it's fitting and good. I also liked both the opening and ending song. There's a song I liked even more, though, and namely Yume no Hero - the original Gridman's opening song - which the original version of we can hear in the last episode and there was also a rearrangement of it played before.
As for the fights, what's much more outstanding about them than the soundtrack are the visuals. The fight scenes are super good and in my opinion they only get better with every episode. The CGI used during them looks clean and good quality and it also makes Gridman and the kaijuu look kind of heavy like they are supposed to be. We also get to see lots of cool transformations and gattai. Many cool combinations appeared throughout the show.
The visuals are great not only during the fight scenes. There are rather many still frames, but I perceive them as an artistic move, which I like. But when things are moving, the animation is fluid, especially when there's a lot of action going on. The backgrounds are full of details, the characters have nice designs (I also love their eyes) and there is nothing about the visual side of the show that I could complain about.
I found the characters to be another really strong point of the anime. Our main trio is totally likeable. Although devoid of some super unique traits, they feel genuine and their actions are understandable. And that's exactly what I like about them. They are just a group of normal high school kids whose everyday life changes because of the strange events happening. One could complain about the main character being bland, but there's a reason behind that, and it's more than just the fact that he has no memories. There's also Akane Shinjou - the girl everyone loves and a friend of Rikka. The Neon Genesis Junior High Students are a crazy but lovable and useful bunch, whose eccentricity doesn't fail to make the viewers smile. There's also a certain kaijuu boy that grew on me over time. The supporting characters are also fine.
As for the references - there seem to be many of them, but as someone that has never been into tokusatsu shows, I can't say much about them, unfortunately. I feel like I'm missing out a bit, but it's not like being knowledgeable about this kind of thing is necessary to enjoy the show. I'm sure the references will add to the experience for people that are more familiar with that stuff, though. I also wanted to mention one thing I looked up before, and namely the background of a certain girl that played an important role in the episode 6. If you are interested in that, I recommend looking up a kaijuu named Anosillus. It's quite moving. Episode 6 is also the one the aforementioned rearrangement of the old opening song was played in.
To sum it up, I see SSSS.Gridman as a show made of love and care for details. In spite of it taking inspirations from other things, it feels like it has its own identity. The quality of the anime is super good. To me this show is one of a kind. Simple, yet interesting and satisfying. I found it to be extremely enjoyable and I highly recommend giving it a try!
