Good directing pulls me in for one chapter and thats it. The story is what keeps me. I won’t read a story just to watch the directing and I dont mind If the story has mediocre directing.
Choices make 0 difference to me.
Actually, choices sometimes turn me off because it stresses me out. 
I’d also rather have a story updated more frequently than have to wait for a long time for super advanced directing, since the longer I wait, the less likely I will continue.
