Edit: After watching the whole season I can definitely say I liked it. Though it can be very slow throughout most of the anime. In the last two episode though it had such a good build up, and even a cliff hanger for a season 2. I take back on what I said about the animation being stiff, but it's alright animation, nothing amazing. So I increased my score to a 7/10 overall because it's good for what it is
---OG thoughts below---
Should you watch it? This is a hard answer. For a simple answer. Give it a watch once and see if you like it.
Story: Its an Isekai which follows a boy who died and his spirit fused or took over a boy of another world. To be honest it seems like another Isekai fantasy, but the story is interesting to an extent. Like he has a goal, a journey, a nation is pretty much against him. He makes a ton of friends. Most are girls which would make you think it's a harem anime, but it all mainly platonic it seems. Like they're just friends. At most a diet harem if that's even the right way to describe it lol. I'm kinda interested to see him prove his OPness to his classmates, and I honestly think that's what's keeping me around. But it has some other elements that are keeping me around not to sure, but I like this anime. It's not like way up there as a favorite, but it's alright.
Art: Let's spend most of the budget on eyes and the hair, making the characters look great, but animation mediocre. Like I love the looks of the characters, but those animations can be stiff sometimes. The only thing that bothers me is Kirito clone lol. I mean he got story which is why I'm not minding it, but can't help but to think Kirito at times.
Sound: Eh op and Ed are alright, but nothing I'd listen to on repeat.
Characters: They have some uniqueness, but I feel the most unique one was probably the little sister demi-human had the most character development so far because of her backstory. Though you have Rio and his story is still growing as it's his adventure
Overall: I'd say I'm liking it so far, but I definitely understand why alot of other could be turned off by this anime. It's really a one-and-done type of anime
