I think this show is a fine introduction to the isekai genre. It's shamelessly unoriginal and I love it for that. Every single trope from the genre is here, from a harem to the video game aspect. I'm actually surprised they aren't fighting a demon lord. But as I've said before I don't think originality is that important, if it's polished to a shine that's also great! In this case, it absolutely is. There's actual character development and intrigue, it's great. The heroes face threats that are actual obstacles. But like most anime, while watching I felt like I'd already seen it. I think most of the villains suck too, but that's neither here nor there. I await season 2 with open arms.
