If it is a good prologue, I'll read it. My favorite series has a prologue that introduces the villains on a quest that the protagonists will later join in on, and that is fine. If it something like "these are my characters!" type thing, or if it has a bunch of information that really should be included in the body of the story, then I'm a bit iffy on reading further. So it is not a prologue itself that I take an issue with, it's how well (or not well) they are written. In my opinion, if someone is going to include a prologue, it should meaningful to the story and well written, because that is the first thing the reader is going to read.
