People keep criticising this anime for being too perverted as if they're watching anime for the first time and ecchi is a brand new thing. Some even going as far as to insult the watchers and labelling them as incels. You don't go into a harem, ecchi anime in hopes of getting a wholesome innocent story, just like how you don't watch Attack on Titan for anime tiddies.
From the title of the anime "Jobless Reincarnation", it already hints that you're going to follow the story of a degenerate. He was an isolated, grown man who stayed at home and watched anime, played video games, and jacked off all day. You can't expect a guy like that to suddenly change his personality and turn into the flawless protagonist the moment he reincarnates. He was a perverted degenerate his past life, guess what he's gonna be the second he wakes up? You see people giving this anime bad ratings because they dislike the main character's personality and the pervertedness. That shouldn't be the driving factor when rating a piece of work. If you prefer to watch a flawless, wholesome protagonists, go watch My Hero Academia.
This story is about a damaged man, an adult who was severely bullied into a reclusive life. Given a second chance at life, we watch him struggle with PTSD and slowly develop into someone with a purpose. He missed out on a childhood, education, friends, girls, love, purpose, etc. in his old life, this is his opportunity to make the most out of a fresh start. Of course that doesn't justify his questionable pedophilic actions, but we know he's supposed to be a degenerate from the get-go. Anime is weird, they've been sexualizing lolis since time, might as well generalize majority of ecchi-harem watchers as misogynistic pedophiles right? Lol.
In any case, the anime does indeed portrays his trashy view towards women as a character flaw if you notice the subtleties in the later episodes. Let's keep in mind this is a guy who isolated himself from society and the only female interaction he has had majority of his life is from porn and eroges. As the story goes on, he slowly realizes that maybe girls IRL don't actually act like the eroge's he played in his past life. Women aren't simply objects that will cater to his sexual needs after he reaches some sort of milestone in helping them. We see his regretful actions after attempting to have sex with Eris, even if it seemed like she gave consent. He comes to the realisation he fucked up right away; the verbal consent was a grey area, her "yes" wasn't really a yes, he shouldn't have taken it as an opportunity to just barge in given how uncomfortable she was, stating he was stuck in his eroge mindset. No excuse, it was terrible, but my guy is learning. Yes, it's uncomfortable to see him have grooming intentions, perv on underaged girls when he's a grown man. I don't believe we're supposed to like this character, nor relate to him. But as uncomfortable as it may be, there is progression in his view towards women and other aspects of his character. View the anime as a redemption arc for Rudeus. We can hate Redeus as a character, but I don't think the anime itself is bad at all.
In fact many of the characters are flawed and develop as the series progresses (his scummy Chad father is an exception). Unlike many isekai protagonists, he doesn't just start off OP, he gets to where he is by working hard and studying. Though after saying all that, I do not see this as an anime that should be considered as something you should analyze deeply into, this is an anime you can watch for mindless entertainment. View it more as a light hearted slice of life than a plot-heavy adventure. If you're too uncomfortable with watching Rudeus at his most degenerate, don't watch it, you won't enjoy it. Getting squeamish people to watch and review a gorey slasher film is gonna garner bad reviews. Getting people who are super sensitive to content regarding sexism and sexual assault to review Moshoku Tensei (or any anime with ecchi) is gonna garner bad reviews. Even though this anime isn't advocating for pedophilia and sexual assault (since they're trying to progress the character and show that these are part of his flaws), many people sensitive to the subject matter will hate on it either way.
Story is entertaining.
Animation is great.
Sound is great.
Overall: 9/10.
