I watch all genres and only watch completed dramas (the wait for the next episode kills me!). Least favorite will probably be musicals and horror (I do watch them from time to time).
When I rate movies and dramas, the delivery matters most to me. For example, a comedy type has to make me laugh out loud often, a thriller type has to get me on the edge of my seat throughout, a romance or slice of life type has to give me all the feels etc... I only rate them when I've finished watching them.
Check out my favorite lists and see if we have similarities or if any is worth you watching.
