I feel like certain dramas are just more forgiving. Like even if the prose is bad and the characters are flat in a sci-fi or fantasy novel, the concept of the world being explored can still be interesting. I love classic SciFi but I don’t go to it for the rich character development.
Meanwhile, drama relies much more on prose and character. If that fails, the central concept rarely backs it up.
I have found I have a personal star-handicapper.
For science fiction, what I watch can dip down to 2-star shows.
For a romantic comedy, I probably need 4 or 5 stars.
Drama needs 5 stars.
For documentaries, having a slew of 5-star important, well-done, insightful movies means little. I still rarely watch them.
