Here's my review of Goblet of Fire, which I just submitted to IMDB.
***** SPOILER WARNING *****
Saw the movie today. Just too many things in the book are missing from this movie. But I think not just details. Most importantly, there is a major underlying theme in the book that got completely left out from the movie. In this fourth movie there is no reference to discrimination and racism, themes that are omnipresent and very important in the fourth Harry Potter book.
The Harry Potter series, and in particular the fourth book, clearly describes the existence of racism and discrimination in the Wizard world. Death Eaters are, among other things, muggle-born haters and despisers. In the movie, however, they are presented basically as just followers/servants of the evil leader Voldemort. Even Hagrid and Mme. Maxime's ancestry of giants is part of the discrimination theme in the books, yet their argument about it, Hagrids humiliation about his ancestry etc., was all completely omitted from the movie. Hermione's SPEW initiative is also part of that underlying theme. Completely omitted too.
Details from the book missing in the movie are plenty, but this is not just another detail, this is a major underlying theme revisited in a lot of what happens in that magic world -in the books that is. Directors simply turned their backs to this topic for the movie. I think this represents a major and seriously detrimental omission. Because of this major omission, I don't think this movie does proper justice to the book.
As far as details in the book, there are quite many missing in the movie. Here a few of the omissions:
(WATCH OUT, SPOILERS)
* Dobby completely missing, Longbottom is the one who gives Harry the braquialgaes (Gillyweed), which is not the case in the book.
* Hermione's initiative to liberate the house elves (S.P.E.W.) is completely missing.
* Rita Skeeter never shown as a beetle.
* Jinx on Hermione making her teeth grow, never happened.
* Argument between Hagrid and Madame Maxime's because of their giant ancestors, missing.
* Hagrid's Screwts missing.
* Harry asking Cho not just to go to the dance with him, but also asking who she was going to the ball with, that last part was omitted.
* Harry's map of Hogwarts, and the scene when Moody asks him for his map, completely missing (and this was critical because it is a point in the book where Harry, unaware of it then, became fractions of an inch close to discovering who was the evil doer inside Hogwarts).
* Harry's dream in Trelawney's class, where Voldemorts gives Wormtail the crucio punishment for his error, missing.
* Apparition of Crouch in the forest highly incomplete and disconnected.
* Neither sphinx nor giant spider in the maze before the cup.
* Hermione catching Rita Skeeter, never happens in the movie.
* Discussion between Dumbledore and Minister after Harry returns, and also Minister's disbelief in Harry's alleged witnessing Voldermort's return, all missing.
* Sirius showing up in Hogwarts in the end, Dumbledore asking Sirius and Snape to shake hands, the shaking of their hands, all missing.
* Money from Harry's championship given to the Weasley's, missing.
* Attack on Draco in the train at the end, missing.
And details in the movie not in the books:
* Out-of-field battle between Dragon and Harry, even up in Hogwart's roofs. This I welcomed very much though. It was an understandable and well done stretching of an action episode and scene.
* Dumbledore being so nervous all the time.
* Harry using a spell to leave the water in the second test.
* Moody giving Harry a hint before he enters the maze.
But still, those omitted details and added ones are minor and really less important compared to the omission of the racism/discrimination themes.
Other than that criticism, the movie is very entertaining, I never felt the movie feeling slow or boring, despite its length. If anything, some things felt crammed. I liked Hermione's acting a lot in fact (but keep in mind, unfortunately I saw the movie translated/dubbed into Spanish). And for once, even with his eternal aloofness, Snape was a slightly likeble character.
I hope the true spirit of the books is better represented in the future movies. The social issues and crude realities chosen for themes in the books even have an educational purpose, and at least for the fourth movie, that purpose was completely ignored.
My vote: 7/10
