Do you think the filmmakers didn't get the reference?
Yes. But that they thought they needed to substitute Irish for Greek - even if they didn't get that it was a wee joke, wtf? Is this some stupid 'we heart the Irish' thing? It seems like such a 
pointless 
change. I mean, I think you may be right about it being some kind of odd ethnic sensitivity - but WHAT ethnic sensitivity? Greeks can't be mentioned? There aren't enough mentions of the Irish? What?

Maybe they thought it was like a Greek Stereotype, and worried about fielding letters from scads of touchy men named Nikos?
Or maybe I just watch the Sopranos too much.(Because several of those characters are  very rabid about portrayals of Italian characters.  It's very meta.)

Hee. I like this. Those Greeks, flogging dodgy monsters (the ones we forgot to nick when we stole their antiquities) to half-giants in pubs. Yep. 
Now if it had been in a 
kebab
shop...
	
 
		
		
Hermione's family bugs me.
We never hear about them.  She sees them about two weeks a year and no one seems to care if she spends all her non-school time with the Weasleys.  I'd love to have a chapter on what it was like for her in the Muggle world.
	
 
		
		
I think Harry should spend part of his summer with her -- because it is odd.
They're proud of her, but they don't want to see her.
	
 
		
		
I agree.  They should spend some time at the Granger's.  Arthur will be very very jealous.
	
 
		
		
I want to know more about the Potters.  Maybe I missed it, but was James an orphan?   Where are the Potters?
	
 
		
		
The Potters
were older when they had James who was an only child.  I guess they didn't have living siblings either  -- or none with offspring.
