I really don't get people that want this shit. Do you not realize that all of that crap is filler AKA stuff that's completely unimportant to the plot, WB shouldn't be getting any shit for gutting it from the screenplay. Quidditch World Cup, I at least kind of get it's importance because pivotal shit to the plot happens there and it's interesting in the sense of showing the audience a taste of the wizarding world beyond England (which Rowling completely wastes but I digress) but the entire St. Mungo's segment is a complete waste of time that adds basically nothing of importance to the plot and in a book where over 80% of it is already filler, that's a massive fucking sin.
The World Cup introduces Krum to the audience and gives scenario for the Death Eater attack.
St. Mungo is not a waste of time: it shows how life is for the other kid who could have been the Chosen One and gives Neville a motivation for joining in DA, also explains why he lives with his grandma and why he's the kind of person he initially is. Neville's not really close to the main trio, but once they discover his secret, he opens up a bit with them and joins them to fight when they go to the Ministry of Magic. The story is not focussed on Neville, but he starts to change after that for the best.
Order of the Phoenix is actually a fantastic adaption for that reason because it scraps all of the pointless side shit except for Hagrid's retarded brother (because Rowling insisted that he would be important to the plot of book 7, LMAO. You can guess how that turned out) but that's still enough to preserve the core of the story. The story is still ass, mind you, but as far as adaptions go, they did a surprisingly good job.
They scrapped very important things, such as Sirius giving Harry the mirror, Sirius explaining about RAB (who is more relevant than Grawp), Kreacher going to the Black sisters, and most importantly, Snape's worse memory. They never showed why it was his worse memory.
They also changed Harry's reaction to Sirius' death and to the whole situation. He spent a full year being kept on the dark and been frustrated (exactly as Sirius), which was the reason Black died at the end. Dumbledore ordered the Order to never give Harry any explanations of anything. Was it that hard to say "Harry, Voldemort thinks a prophecy about you will give him advantage against you, so you need to learn Occlumency for him to not enter your mind and you should never, under any circumstance, go to the Ministry because Riddle will try to lure you there."
Instead, Dumbledore sent Harry with the teacher he hated the most to allow him invading his mind without telling him the reason, which alienated them against each other even more than before, with Harry never properly understanding why the lessons were important (he said it's not a big deal Snape stopped, and he couldn't understand either why Lupin and Sirius were so worried about this). If Harry and Snape had been in a better situation, all Harry had to do was going to Snape and tell him "I've had a vision of Sirius" and he'd be alive.
That's why, at the end, Harry yells and breaks stuff from Dumbledore's office, he's mad at him and at himself. The movie shows him being sad. Harry wasn't just sad: he was MAD. That is a terrible adaptation if you change so radically the emotions of your character from rage to sadness only because you adapted everything else badly.
