Maybe this is the best anime in the world after "Fullmetal Alchemist: Brotherhood". Why? Because this anime has a very complicated story, a very epic dialogue, a plot-twist ending, and a very supportive seiyuu. Due to the very high rating, I will try to review this anime. By the way, this is my favorite anime. Also, I usually rewatched how many times because it gets boring.
"Steins;Gate" has an impression of a very slow plot. For people who are very unfamiliar with this anime will not be able to survive watching this anime. In episode 4-6, you probably will not understand the plot. But, you must be patient because maybe you will be very interested to watch it considering it's has a very high rating. Starting from episode 13, you will instantly get carried away due to its fast-growing plot, many explanations about a time machine, time shift, dystopia, and things to be explained very well. This is what makes this anime very interesting because the thriller side is very shocking and gripping. Perhaps, for those of you who love physics, I recommend this anime.
"Steins;Gate" has a very interesting visual because of it's very abstract, simple, and very simple graphics supporting the thriller and mystery genre of this anime. I don't know according to the people, but after reading the comments and reviews they judge the visual because it's very simple and not very interesting portrayal. For me, the graphic is very interesting. But, back from the perception of the people who watch it.
Although this is an anime fiction and thriller, there's some comedy that will make you laugh. How not, Okarin, a mad genius scientist who has a chuunibyou (called "eighth-grader syndrome" in English) character or often fantasizes as a crazy professor makes Okarin very unique as the main protagonist. Mayuri who has a very childish but always help Okarin, Daru as a hacker and friend of Okarin, Kurisu who have the nature tsundere (a person who is initially cold and even hostile towards another person before gradually showing a warmer side over time), and much more side-by-side characters.
Mamoru Miyano, the voice of Okabe Rintarou character is a very genius in filling a voice in this character, remember in the anime, he always says "El Psy Congro" a slang to end the sentence while calling. Hana Kanazawa, who filled the voice of Shiina Mayuri had a similar slang like Okarin "~Tut Tu Ruu~" a slang for a 'hello' replacement when meeting his friend and saying it in a very cute tone. They are both my favorite seiyuu.
Overall, if you are a fan of a sci-fi story, you might be interested to watch this anime. But, as I said, you have to be really patient and focused when watching this anime because few of you will be really fooled and don't understand the story.
