There are a lot of strange unexplained events that seem really off, and there's practically no character development at all. The romance feels like it came out of nowhere and all the girls, which by the way feel really shallow, immediately love the protagonist and trust him without question.
I personally feel like the story could have been longer and could have been made in a way that made more sense.
The show doesn't really have much fanservice (in terms of quantity), but when it decides to include some, they go all out. There's a scene where one girl is completely naked, but that's pretty much all the fanservice in the entire series.
The characters are really shallow, and additionally the protagonist has random super concrete knowledge on seemingly random things. It seems he just happens to know the entire periodic table by heart, including all the specific characteristics of each element, but it isn't a constant theme. He suddenly is an expert on the subject when he needs to, but then doesn't know more than a regular everyday person when he doesn't. It's just inconsistent
The animation is ok, although they could have made better use of 3D animation. They use it for unimportant shots, but somehow it always ends up looking weird.
It's an okay watch if you're bored and have nothing else to watch, but I would personally recommend you watch something else. If you're really interested in the story, I would tell you to go read the light novel, which I can only hope is better.
