Getting it right in the films (Was: Question for parents)

[va32h]

Carol:
That I didn't get, either, or the tongue-twitching, which I found
annoying and unnecessary.

va32h:

This was to hint to the viewer that Crouch Jr.  was Fake!Moody. 
Fake!Moody  has the same twitch.  And when Fake!Moody encounters
Crouch Sr. he gets agitated and twitches...and Crouch Sr. recognizes
him which is why Crouch Sr. is dead in the next scene.  But that whole
thing is badly done - I've watched the film with people who haven't
read the books and they didn't even realize Crouch Sr. *was* dead. 

GoF on the whole is not so much a film, but a really, really long
trailer! 

I have never minded having the kids wear Muggle clothing.  All the
characters running around in shapeless black robes would be very
boring visually.
