The best one in the series so far. Adam professed to prefer Prisoner of Azkaban as more "uniform" thematically, but I just adored GoF. Some of the previous Potters seemed much longer than they actually were, while PoA suffered less from that syndrome than Chamber of Secrets or the Philosopher's Stone, Goblet of Fire at a solid 2hours and 20 mins actually left me craving for more. Many kudos and other congratulatory type stuff to Mike Newell!
Twas a collaborative affair between me and M. Ashwin reminiscent of Charlie and the Chocolate Factory. Although in this case due to the looming exams, I had toned down quite a bit. Still we had the usual suspects and quite a few additions; including a flying visit from Scintillating Cyn who had technically moved to Bangkok.
Back to the movie; I loved the visuals, they were spectacular. The Yule Ball was far too short for me although they could have done better with the Patel sisters' lenghas. Dumbledore's eulogy for Cedric at the end actually gave me goosebumps. Madam Maxime could have used a bit more horizontality I felt but Rita Skeeter was perfect. Emily Watson has become far too pretty as Hermione which of course served her well in the Yule Ball. There wasn't enough of our favourites of course, but that's only to be expected, I guess. More of Snape and Mcgonagall should be evident in the following films. The new Dumbledore continues to disappoint though, I wish they had managed to beg Ian McKellen to take it up. He would have been quite perfect especially in light of the most recent Harry Potter book. 
I must mention again the Patel sisters' fugly lenghas, which was pissing off especially in light of Cho's gorgeous cheongsam. So the costume designer understands cheongsams but not lenghas? Fred and George were an excellent piece of casting. Thankfully we got a bit more of them this time, although Lee Jordan was sadly absent but there were no Quidditch matches this year because of the Triwizard Tournament. Ron is becoming an excellent actor as is Hermione (which only brings Daniel Radcliffe's mediocrity to the fore)
Argh. The evil 'net lost most of the second half of this post but in light of the frequent complaints about brevity; especially the lack thereof, I shall say no more :-p
