I get what Isekai should be about, it's about someone or something thing got teleported or reincarnated into a new universe or new dimension.
But That time i got reincarnated as a slime takes it and makes it amazingly shitty anime with cult like structure in which a shitty protagonist tries to something and the rest of the character just follow, it's like the character doesn't have any personality or willpower they just sucks! And follow the MC
Anyway let's talk about the comedy it's soo amazing not funny that i slept just by listening the stupid dialogues.

Fantasy genres that suppose to give you the experience of creatures, gods, imaginary beings that are new and native of there place but That time i got reincarnated as a slime just picks up the most common creatures and the freaking "Demon Lord" concept it's just so overwhelmingly bad!

I get it a slime demon lord is new...but the most powerful..its just that when you smack your head on rocks you get this type of ideas.

Let's just look at the character 'Milim Nava" she is a cool bad ass with awesome power. And what happen to her....got enslaved by the freaking honey, i mean if she wanted to she could just destroy the forest and then compelled rimuru to give her the formula. She literally have the nickname "Destruction" and what I told it's a cult!!!!!

Now it's time for the protagonist Rimuru Tenpest, his real name Mikami Satoru, was just a ordinary virgin office worker before he died protecting his friend's girlfriend. he was pretty smart, his dying wish was to erase his computer hard drive! (Most common type of MC in isekai anime no originality)

Well it's good that the protagonist is very overpowered but that character development sucks soo much i can predict pretty much what is going to happen next. The story is pretty lame ohh sorry i meant the lamest! Those stupid comebacks, moves, realising some old friends memories and getting OP...#Lame

"Log Horizonhttps://anilist.co/anime/17265/Log-Horizon/)" anime got the same concept as this one it's isekai, fantasy and it's way better than this. The character have personality and amazing development!

Another recommendation, Konosubahttps://anilist.co/anime/21202/KONOSUBA-Gods-blessing-on-this-wonderful-world/ if you haven't already watched give it a try its amazing and refreshing!

I guess no matter how much the protagonist is OP if the story isn't good everything falls apart just like this anime.

If it would just be me writing my stupid review based on my own desire to see something awesome with the score of #87 and got disappointed coz of wasting my time on this, So I asked some people about this anime chatting groups what's there opinion on Tensei shitara Slime Datta Ken (That Time I Got Reincarnated as a Slime)
Most of the told me that this anime was boring and the animation was not that good either except for the first episode, So if you really wanna watch something stupid and to pass time than and only than you should consider this!
