I agree that Francis didn't come anywhere near John Paul II.
But we don't know how Leo's papacy will play out and what he will achieve. He could come close to John Paul II, we can't decide right now that he doesn't.
When Pope John Paul II was elected he was a "shock" election, no one had heard of him and then he went on to be Pope for 26 years.
He was elected when I was 2 so I grew up with him and became very fond of him and he was there for the next 26 years. When he died I was very upset. I'd never known anything else but Pope John Paul II.
It's hard to feel the same about other Popes because I didn't grow up with them, they came along later!
Let's see what Pope Leo does.
