Review Detail of Splooj in An Extra’s POV

I was so bored and frustrated after the first 20ish chaps I couldn't bring myself to enjoy the story finally focusing on the mc. Some reviews say that the beginning is a non cliche masterpiece with well developed characters and world building, but if you've read even a couple of jp isekai novels, it's nothing new. I'm not going to say it's a direct copy of anything in particular, but so far, nothing is new or anything close to a masterpiece. Don't read the review', and maybe you won't be let down and can enjoy this more than I did...
