Prologues can be boring if not done properly. As @migxmeg said, prologues that feel like prologues are very tiring to read.
One of my favourite ones is from 'The Alchemist'. I was honestly taken aback by the fact that it was only the alchemist finding a book in a caravan and finding a story about Narcissus that was barely a page long.
That was it! The version of the book I have only had a page and a half of prologue and it was basically there to make the reader wonder how this plays a part in the story.
That 'wondering' plays a huge part to get the reader invested!
If your work is a fantasy, then a prologue might help, but they are so easy to mess up!
So, the prologue is only there to entice the readers to read the story, to show them a bit about the world so that they go into reading it feeling like they know a little bit about it.
In the end, it's your choice. See how you'd feel as a reader. If you think a prologue is needed, keep it. If not, there's no need at all.
Hope it helps!
