I think it is very good of these people to point out the bad things involved as well.Yeah,even i felt that Ron was shown a bit fearful even near the whomping whillow scene(actually he is scared of spiders,But why Whomping whillow too?).When i was watching the movie in theatre,everyone were laughing at Ron.But now in POA....This is really bad of the script writer(i dont remember his name)to change the lines of Hermione and Ron.It will affect the later movies and the charecters as well.One of the persons here quoted a good point here.In cos hermione says "fear of a name increases fear of thing itself".Actually Hermione never talks to Lucius malfoy in that scene.
Well done!
