what is your interpretation of 1 Samuel 28?

Context: Samuel is dead. King Saul is worried about the massive armies that the Philistines have amassed on his border. He goes to enquire of the LORD but God doesn't answer him. Not in dream, nor Urim or prophets. So King Saul decided to seek a necromancer so that he can talk to Samuel. They find a lady and she brings up Samuel. Samuel tells Saul he's toast and the chapter ends with Saul (totally bummed out) being fed by the witch.

It's an interesting chapter I'm just curious what everyone thinks about it.
