Well i understood this movie perfectly well because i've read the book about a million times, but it struck me that people who havent read the book might not be able to understand it, especially the bit where Dumbledore and Voldemort's wands connected in prior incantatem (which should only be able to happen between Voldemort and Harry's wands)
well anyway.. one of my "non-hp-reading" friends told me tht she didnt understand it at all, and she had to ask "wat the fudge was that prophecy all about "
i think they should of done what they're gonna do with the 7th movie and make it into two movies so that they can put in all the proper information.. and they should have done that with the fourth one aswell because they actually missed out two characters in the goblet of fire movie (Winky and Ludo Bagman)

I just think that this movie was the worst one so far, and i feel quite let down as i had such high expectations of it, for it was my fav book in the series (until the 7th came out:P)..i just hope that they make up for it with the 6th one
