First, I agree, Snape is not a good teacher, even though his classes 
seem to have learned much more than they realize. And they've learned 
enough that away from Snape, they perform better. It says something 
that OWLs are less stressful than attending class!

But IMO, Neville is a special case. I don't think McGonagall is having 
much luck pushing him to potential either. And she's gotten irritated 
enough to be sarcastic with him. I'm away from my books, but I'm not 
sure if we know how he does in Charms with a kind teacher like 
Flitwick. It seems it's Seamus who has trouble in there. (Or is that 
movie contamination?)
