I've never seen "Schindler's List". Is it any good?

No... I would avoid the director at all costs - I can’t see much difference between Spielberg’s serious movie and his boy’s book movies. Schindler’s
List depends on Spielberg’s inflatable, one-size-fits-all myth
about how a clever, resourceful character can outsmart a system.
Is that what the meaning of the Holocaust boils down to-Indiana
Schindler versus the Gestapo of Doom? That’s what Spielberg’s entire
world-view amounts to, as far as I can tell. Stylistically, it’s the same old comic-book sense
of life: Schindler’s List depends on the same formulaic
responses to formulaic characters and situations that Jaws did.
We live in a culture of mass-production and one of the products
we manufacture the best is synthetic emotions and experiences.
The Hollywood studios are brilliant at massproducing stock feelings.
They have perfected the art of canning them.

Yes it's a great film. You should look at The Boy in the Striped Pyjamas , and Sarah's Key also for other good films of this genre. They are both fictional I think though.
