This site brings up some interesting ideas about this movie that I had not thought of. Not really an analysis, but interesting ideas no less.
This New York Times article talks about how this film represents leaving childhood and has lots of adult tones.
In the beginning with Frank Bryce (Eric Sykes), the old man at the house, he is trying to be a good person and take care of the property, i.e. kick people out who shouldn’t be there. But he does not expect a man who talks to snakes and kills people with a wand. Evil is a presence even for the muggles.
Also, when Barty Crouch Jr. (David Tennant) sends up the “dark mark”, the ministry members try to attack Harry (Daniel Radcliffe), Ron (Rubert Grint), and Hermione (Emma Watson). The ministry is supposed to be the good and whoever sent up the dark mark is the bad. The ministry thinks the three main characters sent up the mark, therefore they are bad. However, we know that is untrue.
Even the introduction of the unforgivable curses could be seen as good versus evil. The Moody impersonator says these curses will “earn you a one way ticket to Azkaban”. So far in the years before, the students have learned good spells: how to levitate things, unlock doors, and light their wands. But now they are learning about control, torture, and death.
When Harry is in Dumbledore’s (Michael Gambon) memory, there is a clear line between good and evil. Good is the ministry members outside of the cage in the hall. Evil is the death eater inside the cage.
Obviously, when Harry is in the graveyard, there is a major struggle between good and evil. Wormtail (Timothy Spall) kills Cedric (Robert Pattinson) right off the bat. Then it turns into a literal duel between Voldemort (Ralph Fiennes) and Harry.
Also, the Moody impersonator, Barty Crouch Jr., and the real Moody (Brendan Gleeson) are at odds with good and evil. The real Mad Eye is a good wizard. However, Barty Crouch Jr. is trying to help bring back the Dark Lord and kill Harry.
This battle between good and evil shows how easy it would be for anyone to take the easy way out. Leaving problems alone and not fighting for life are passive paths the characters could have chosen, but they did not.
SIDE NOTE: I thought of this while I was watching this movie. This movie has a lot of King Arthur lore in it. Cedric’s dad (Jeff Rawle), says “Merlin’s beard” when he meets Harry. Also, the Goblet of Fire is a cup like the Holy Grail. During the tournament, Harry is on a bit of a quest, too. This may be a bit of a stretch but, Cedric is like Arthur in that he is superior to Harry in knowledge and age. Cho (Katie Leung) is with Cedric making her Guinevere. And Harry wants to be with Cho (he asks her to the dance) making him Lancelot. There is no adultery, but the two stories have similarities.
