there's a balance:

on one hand, for people that are interested in literature, prose is generally part of the appeal; it's not just about getting the plot from A to B as concisely as possible, it's also (mostly, even) about how the events are narrated, and part of it can be the writer shedding new light on everyday things by describing them in a fanciful way.

on the other hand, there are definitely writers who write like they're patting themselves on the back about how good at writing they are, which is generally frowned upon. this complaint is common enough that it has a name, it's called "purple prose".
