Mushoku Tensei is a tough one to review. To be concise, it was an anime where I liked some things and hated others, making it very confusing.
Story (6/10):
The story is... well. I understand that there is probably a big plot hidding somewhere (and I can begin to guess what), but the pacing is... well... not really good. I would have liked to see more things "story-wise", but things seems a bit rushed, and too much focused on useless fanserv (there is far too much of it) and barely legal/moral things sexually speaking (I look at you, Rudeus). I think I would have enjoyed the story a lot more if it was more consistent and developed, more profound. Well, LN readers say plot is better after, so wait and see.
PS : I know in medieval times it was a thing for young girls or boys to be married with older people (or with another young). It could be part of the setting, I understand this. But as always, there are WAYS to present a thing without making it utterly awkward and far too present in the story, to the point of ruining it.
Art (8/10):
The art is really good. I can not say otherwise. We can see the classical "light-draw/less-detailed in background" things, but it is globally really beautiful. This is clearly a strong point of the anime, and the first episodes in the medieval villages were really, really beautiful art.
Sound (5/10):
The soundtrack of Mushoku Tensei is not bad, but not good either. I had not a single theme I would like to re-listen after viewing the show, and I'm not really remembering any music in it. But it also means it was not shocking nor bad. So average, it's a 5.
Character (4/10):
Frankly speaking, some are likeable, and some not. Some deserve a 1 or 2, others a good 8.
In fact, there are a lot of them that are generic or stereotypical, but it is not always a bad thing. Even some of the "fanserv" oriented scenes are good. It makes the characters more reallistic, for some. Like, Paul is a real idiot and sex-oriented guy, but is enjoyable. Roxy has problem with her sexuality has a demon 100 years old, understandable again.
The real problem I have with the characters is the over-sexualisation of them. Like, all the Rudeus-things. In fact the show would be so much better without Rudeus (it's horrible to say that, cause he IS the main character... welp). I'm not totally AGAINST fanserv. But when it made over 90% of the character, it is at least boring, if not utterly infuriating. I mean, OK we understood Rudeus was before a bullyied man, with a shit life, shit moral (almost a pedophile it seems). But making it a perv directly as a baby, having a panty cult, being drived only by sex even if it's with children, well, no ? There is faaaaaaar too much perversion in this. A LN reader explained me that the whole point was to make him becoming a "good guy" after starting as a "bastard-perv", but GOSH, there are other ways to make viewers understand this. Currenlty is is really dragging the show away and make it far less enjoyable that it could have been.
Even the prince we don't see often, the one Roxy teach magic after, is so FUCKING A PAIN. I mean, YEAH you can make him a degenerate perv, but in this case it's not even that, it's so STUPID that it makes him unrealistic and cumbersome. Really, almost all the things related to sex in this show are awkward, if not ruining the show and characters themselves...
Ah, and yeah, Human god sucks. What the hell is this voice and attitude ? This guy seems to be a crucial part of the plot and setting story, yet is one of the most stupid and bad-writted character ? What the hell ? LN readers said me he is supposed to be a "scheming guy" "manipulative"? It's a clown. If the aim is to make him "play" the buffoon, at least give him something to be relatable.
Enjoyment (5/10):
Frankly, when I saw the few first episodes, It was really enjoyable. Like, the Greyrat family, young Rudeus etc, some of the stepstones that make characters grow. After that, the story went in different directions, fast, but without providing things I would have liked to see, that would make the setting more immersive. Really, Rudeus killed my enjoyment. He DID good things. He did some enjoyable things, really, and his character is step by step evoluting (we can see that in the last episodes). But the far too-present perv-side of him really put the mood down. Like, when I saw the first episodes, I was always like "Yay, super beautiful settings, likeable characters in fantasy settings in their life and... WHAT ? NO RUDEUS STOP FANTASIZING ON YOUR MOTHER BREAST. NO STOP WEARING PANTIES LIKE A BABY PERV WHILE SMILING IN A DISGUSTING WAY AT GIRLS." Always that. Good mood, story advances, then BANG, Rudeus perv for you, insta-killing your enjoyment.
Overall (6/10):
The average of my notes is 5.6, so overall it's a 6
For me, this show HAD potential, but it has not blossomed yet, and the few we have seen is often ruined by the perv-side (if not degenerate) of Rudeus.
I'll wait the sequel in order to determine wether or not this show is worth the praise or not. Cause currently, it is not, but it let some hope for the future.
