SPOILERS!
I saw it on friday. I think it was a better film than the third one but my favourites are still number one and two.
Okay, one should always start with something positive.
The three "kids" were good as always. Snape was good as always. The dragon was fantastic as was the maze at the end. And I loved the scene with Malfoy the ferret.

I also liked the fact that the Weasley twins had a larger part. The scene when Harry comes back with Cedric's body was very good and emotional.
I think if I had never read any of the books (like the guys who were sitting next to me - they were really surprised what was going on

), well, I think I would have been really pleased with that movie. It was action filled from the very beginning until the end. I didn't realise that I had spent over two hours watching it - and this is usually a good sign because it only happens when something is extremely entertaining.
But I missed the special sense of humour for which I love these books so much. What have they done to Dumbledore? In some of he scenes he is not much better than Snape. When he shook Harry I just thought: Something is wrong here. Dumbledore has always a very special sense of humour - and it seems they have forgotten completely about it. I don't know who to blame for it - actor, director or screen writer. But I had that feeling already while watching the third movie. I didn't thought Michael Gambon was a very good choice but there wasn't much to do for him in the third part so I thought I'll give him a second chance.
Maybe you think I'm a bit too much in love with details but I think detail is what makes these books so special. And Dumbledore was always one of my favourite characters and I think they have ruined him.
Something else I disliked was the simplifying of the plot but I can understand that this was necessary. Although sometimes I ask myself if filmmakers think of their audience as "stupid" and that's why they try to make movies not too complicated.
But again, as in the third part, the mystery was solved long before the end of the film. A big part of the surprising end of both (book 3 and 4) is given away somewhere in the middle.
Voldemort - I'm sorry, but I don't think he was very scarry. I had imagined him much more snake-like. As for Ralph Fiennes, I think it would have been better for him to give him another make- up. I was really looking forward to him playing Voldemort but I think he didn't have much of a chance to show how good he is. (maybe his voice was impressing - I read a few reviews about how good he was while giving his little speech. You have to tell me, for I have no knowledge of his original voice.)
I think this is no real critizism because it's very personal. I just had a certain picture of Voldemort in my head and obviously the director had a different one. Same goes for Moody.
The Quidditch stadium: When I saw it I just thought: "WOW!!!!" And then they didn't play! I was so disappointed. They spent work and money and computers on that fantastic stadium and then they don't even show a bit of the game. I hope there will be a bit more on the dvd.
The maze: Like I said, it was amazing and I think, really scarry. But I had really liked to see the giant spider or the sphinx or one of Hagrid's Blast-Ended Skrewts.
The Death Eaters looked a bit like members of the Ku Klux Klan in black robes. But I think that was a very good choice, given their activities.
Now, it maybe seems as if I didn't enjoy the film at all but that's not true. I had a lot of fun watching it. It is definitely a very good film but given the amazing and complex book I was a bit disappointed concerning the storyline.
Yes, I know, I concentrate way too much on details. But sometimes I think a movie needs them.
