I think it is important for the story to be slow enough to fully explain the world and develop relationships naturally.
I write romance novels and although I like a fast, smutty read as much as the next person, I appreciate when I story takes time for the characters to develop a relationship naturally. This doesn't necessarily mean that a long time passes in the story time. Simply that there are enough scenes to make the romance believable. For example, the events of the "The Wedding Date" by Kit takes place over the course of 5 days, but it is a full length book.
My own story spends over 50,000 words on the first week, but I'm also writing a longer form novel. I don't like scenes that don't advance the plot or serve a purpose, so I try to limit the amount of tedious or daily tasks my characters are shown doing. In theory, every scene should be written to advance a relationship or develop a character, but some people may think my writing is too slow. It's definitely what people would call a "slow burn".
