Anyone else disappointed by the ending? (Uncharted 2)

The final boss sucked, but it's Uncharted, so I expected that. Hey, at least it was better than Navarro: take cover, roll, jump, brutal combo, brutal combo.

One major plot hole I noticed:

Somebody said that some of the most powerful men in history had possessed only a fragment of the stone. But there was no stone! What did they have, a jug of tree sap?

And some others:

If the sap makes you immortal, I can perhaps understand the sap killing you, but why did a single shotgun blast from Lazarevic kill the two guardians?

How did Sully manage to find a remote village in the middle of the Himalayas?

Shut up, it just a movie! 0_o
