This review contains no real spoilers, but gives you an overview of why this show is just bad.
I first want to mention that a lot of anime in general is made to sell, but not made to be remembered very fondly, critically, or seen to break what can be accomplished in the genre. Basically just made to cheat people out of money. Tensura is exactly on of these series.
The rotten tomatoes score for this movie shows you how the anime community has lost all aspects of critical thinking. Tensura has one of the worst rotten tomatoes critics score I have ever seen and an extremely poor performing box office despite shown in every theatre. FYI, movie critics are usually nicer on anime. Yet we are supposed to treat this series as the equivalent of a citizen kane. Anyone saying this is some sort of masterpiece really needs to review high school literature classes.
Tensura has become the junk food of anime. It looks tastes good at the beginning, but gets bad when you leave it out. It is easy to produce, and full of just bad stuff. It makes a lot of money, but is bad for you.
Isekai has become nothing but a unique hook to keep you in the beginning. Than suck the viewer in with abysmal writing as the show gets worse and worse. Similiar to the CW.
This series is nothing but a self insert fantasy for hikikomori to be overpowered and have a harem. I want to emphasize I have nothing against harems, but they need to be properly written and have substance. It is isn't clever or witty, it is a generic power fantasy of a video game setting rpg. No wonder Japan has a collapsing birth rate and foreigners are taking all their women.
This series has the all the ingredient of a bad show. Predictable plot, bad pacing, deus ex machine moments, pointless talk, no plot build up, no emotional moments.
Rimuru is one of the worst written anime characters in existence. He literally serves as nothing but a sex doll for big breasted female milfs or scantily clad lolis. He lost all substance in season 1. But he looks like a girl that is okay. He faces no hardship. He oneshots all of his opponents. Just an extremely overpowered. All the characters treat this guy as he is jesus.
Milim and Shuna are appalling one dimensional characters with next to no substance and history. Aside from fighting.
The villains are the one typical dimensional jackass. They come, get one shotted, you forget about them. They don't have substance or backstory that connects with the others. This pretty much happens throughout the light novels.
This series recklessly introduces a dozen or so characters, gets rid a chunk of them. This is pure bad writing at its finest.
The episodes are extremely dragged out with a lot of fluff talk that lead to nothing and no major part. Some episodes only involve characters talking. But the dialogue isn't witty, thought out, meaningful. So it is just people yapping; it is just filler. There may be a fight but it lasts pretty short throughout a season and has people yapping for the rest of it. These episodes make the cw shows feel like shakespeare. You can pretty much watch this show in the background while you play around on your phone.
The humor is extremely forced. It isn't good verbal humor nor situational humor. It is not even edgy humor. They just act silly for the sake of trying to make you laugh which never works.
The plot pretty much turns into nothing more than a hack and slash battle rpg.
I have saved you your hard earned time from trying to invest yourself in the series. It is a series that pretty much continues to get worse and worse as time passes. Might as well go play final fantasy if you want to immerse yourself in the fantasy experience.
