It's okay. 7/10, as it's interesting for a first episode. Not revolutionary, very "Artistic Light Novel" in the variety of artist detail, but also convenient world building, if a bit risque / adult. Not as terrible as it could have been, given the 50+ Isekai's a year, with standouts like Log Horizon / SAO etc.

I can't tell if the show is generic or has potential for an 8/10 story or character development(s), or if it falls hard into Isekai trope/cliche's, as Seasonal Anime trends towards boosting the quality of the first 2-3 episodes as review scores affect viewers & marketing numbers.

Isekai as a mid-budget seasonal show tend to be weak on characters and story, and often fall apart within 3-4 eps, but IMO Jobless is worth checking out if only for the art style, slightly reminiscent of Grimgar and Black Clover, and they didn't really change the formula, it's Adventurers with Magic, but at least it's not Orphans, Magic School. Slime/Spider/Vending Machine reincarnations, or Adventure Harem (yet).

It's probably going to be Adventure Harem with a strong art direction. Which is a good niche to fill, IMO that's not as sedentary as Grimgar or as ridiculous as Arifureta / In Another World with my Smartphone / Cautious Hero, etc. It's probably somewhere in the middle given the 'realism' setting.

After the character turns 5-6, there's actual character depth for a "reborn 40-year-old NEET", this may be obscured once he grows into a ~50 year old teenager with issues, YMMV. Truck-Kun made an appearance, so you know it's going to be on the edge of parody that isekai's often teeter over, or just jump right into the fantasy without looking back to see if people have followed along.

It is going to be a challenge to see where the weak point is - the Art budget, the characters, the story depth, or the Arc / Premise, since they haven't really developed the background. Direction seems to follow LN convention, so hopefully the characters aren't dull.

Until they finally get that vending machine Isekai Anime happening, it's a little better than the January 2021 season alternative "So i'm a Spider, So What?" IMO, both shows could excel. Time will tell if "Jobless" or "Kumo" will improve or settle into mediocrity.
