This show features all the worst tropes an anime could possible feature. It is masturbatory male power fantasy with a giant harem of girls fawning over the main character's video game skills.
What if I could live in an mmo
what if everyone was FORCED to play it with me
what if i was the chosen one
what if women were amazed about me being the chosen one
It is basically your dream. But is that necessarily a good story? In this reviewers opinion, the answer is no. The only original idea in this show is the setting where a lot of people are stuck inside a virtual reality mmorpg, and it honestly doesn't play that large apart of the story. Sure they talk about it all the time, but the mmo is set in a generic fantasy universe, so the anime is basically set in a generic fantasy universe too.
However, I must admit, I do think every single trope of anime is in this somewhere, so if you only care about watching the same retired stuff over and over, this may be a show for you. There is a cute girl with a pet, there is a pervert male sidekick, there is casual incest, every woman in the story serves the purpose of damsel in distress for the main character to save, there is a way too long Ross and Rachel like love story which only culminates into a kiss (I am not saying it should be a hentai, but at least implying a sexual relationship seems appropriate at some point), and don't worry, there are plenty of filler episodes to explore each and every single one of these bland ideas.
I guess the art is good. It is not very artistic, but it seems to have an okay budget, so they have a lot of animated action sequences, which I guess is cool.
Other than the art, the story gets the highest score from me. Just pure power fantasy is actually a very popular story, which you will meet in a lot of pop culture, it is just not for me.
When I watch shows and anime I like at least some kind of originality, and not just a "wouldn't it be cool if a girl was forced to play video games with me"
