Review Detail of Slesk in Naruto: The Strongest Kakashi

So I read up to chapter 12 and honestly it's garbage. The only thing going for it was length of the story but a long story does not a good one make and this one is very not good. The thing with the sword in chapter 12, the thing with the the spiritual energy making a sharingan eternal, or even the spiritual side making it evolve into rinnegan despite their evolutions being already explained in canon. There are a bunch of other annoying points I noticed and that was not even a tenth of the way in. So I figured this isn't for me and to drop an honest review of what I felt like. I'm not dissing anyone who likes it but this is clearly not a work I enjoy and I don't see myself picking it up later.
