Laughed way too loud at "NEEERD!"
A lot of these are explained by reading the books. Eg- Filches cat is petrified because it sees the basilisk in a reflection, not because the basilisk was aiming for killing the cat. Probably 3/4 are solved by a more true analysis of the book and not just watching the movies.
I've read all the books before seeing the moviews and my brother at one point stopped talking to me because I kept coming to him with logical error after error in the books. I was so angry and fed up with the idiotic behavior of the teachers as well as the things they said and did clearly making no sense at all.The books are just as bonkers. The only way to not get riled up about the weird behavior and lack of real rules and logic in these people is if you say to yourself what my brother kept telling me: "It's magic". Everything is always explained away with "magic".The movie basically blatantly shows the logical errors more clearly because you can't just make up something that would fill the holes in the story in the books yourself, by pretending there's something that simply prevented people from acting more sane. And in the movie you simply can't because a pile of rocks is a pile of rocks and a door with snakes on it that got closed is a door with snakes on it that got closed.Here's just ONE thing that makes me go mad in the books: the point system. It's so completely f***ing arbitrary I kept wanting to punch somebody.
a note: this movie is an /adaptation/ and a lot of things were left out which means that half of the things in this could have been explained by reading the books.a few things:1) hagrid's roosters were all killed by ginny.2) the students were /terrified/, harry started speaking parseltongue and they all ditched him like "oh my god heir of slytherin oh my god let's never talk to him ever again"3) rules of polyjuice potion: one dose (one glass) is one hour. they made enough for three people. don't see the problem.4) its not like draco malfoy walks up to dobby and dumps a basket full of clothes on him. house elves work in hogwarts too, and they clean all the rooms and cook all the food and all that. draco probably just snaps his fingers and orders dobby to take his clothes. for god's sake, dobby /ironed his own fingers/. obviously he can touch clothes and clean them.5) and of all the things, i honestly don't understand why you're not mad at dumbledore for pulling shit on harry like all the time. it's like painting a portrait of a person without a face and then saying "oh hey that dude's missing a strand of hair." you're just grasping at straws for half of the video. and gah.on a side note: the points system irks me too. it's basically the sucking up cup.
