TLDR: Well, it's better than bad story with good animation.
Let's get the cons out of the way:
- This is the laziest animation I seen this season and I just watched "Bye Bye Earth". Photoshop filters to make backgrounds look like bad artwork, CGI mobos... Hell even the main character and support were bad CGI at times.
- Cliche premise. For some reason Japan is obsessed with transporting an entire class to another world. This time they didn't even bother with being hit with Truck-kun. They were in it. And yes, our beloved MC was the weakest who get separated and became the strongest so far.
- The writers goes out of their way for you to make "evil" characters hateable. It is very cringe and jarring.
- Low IQ plot that's been done before so many times.
- Tig bitty elf girl. Everyone like big bouncy ballons and a pretty face but needles exposure and unnecessary nude scenes cheapens the story.
- Stupidly OP MC. The few times he got hurt later on, he really didn't have to. The over dramatization of fights where he basically single combos the monsters just took away from the moment.
There are Pros:
- The MC is flexible and not bound by a holier than thou code. This leads to some "practical application" of his skill set, which is often lacking in these types of stories. ie the dead don't talk and sometime venges is necessary. He stays low key and doesn't get wrapped up in a whimsical romance. So, the story is not a complete bust.
- Voice acting and sound was decent enough not to distract you.
- Decent pacing keeps you engaged while not rushing through plot points.
- Only the second time I've seen the mechanic "his class is so low he gains XP very fast", which makes sense.
- The world is diverse enough not to have you sleeping away.
- At least a few characters got a back story explained.
All in all, this is worth a watch for isekai fans but it not something to rush to. The only reason I it gets such a high score from me is the MC does what need to be done, which tickled my fancy bone. Otherwise, it's a solid 6.
