Discussion CN with perfect mc are garbage

Why can't CN mc be normal with bit of trying...most mc specially with a system can do everything, if it's about entertainment novel, the mc will sing, dance, play piano, write movie and songs, play the acter and the actress in same time, direct, produce a d what ever else . Plus Everyone are OK with that.. If it cultivation novel then the mc will be perfect in chemistry, fighting, laws, médecine, the illusion stuff that I forgot it's name where they use flags and what ever... Anyway some novel are well written you enjoy them even with the mc being perfect but in most I don't understand how can someone relate to them with their inhuman reactions... For example "mc enter rich girl house and doesn't feel anything, ofc if it happen to xx a week ago before his personality change he would, bla bla bla.." like can't mc be bit human, react normally and not perfect robot... It's get boring and uninteresting and I feel annoyed about how they win every award in every field against people who worked hard...

 

Not all cultivator MCs know something other than fighting, but if they do, they excel at it.
If they only know how to fight, they'll essentially be considered as brute who only know how to fight.

 

Same could be said about Japanese novel MCs being dense, naive, and beta & Korean MCs being selfish,money hungry, and antisocials that solo everything

 

What's your defintion of normal? Because normal is subjective. Talk to five people about being normal and most likely you'll likely have different answers.
And why bother reading normal things in fantasy series and novels? What's the hook in that?
