Scientifically, an eclipse is not particularly interesting. We know how they work, why they happen, the lot.
But the thing about science is that it is a human endeavor, above all else, and there’s precious few humans who can see darkness at mid-day and not be moved. And a precious few who’ll see it more than once or twice in a lifetime.
So no, they are not rare if you are a planet. And not special at all, unless, of course, you happen to be human.
