Harry potter 1-3

So far I've only seen movies one through three of harry potter. My favorite out of all of those is prisoner of azkaban i think that is how u spell it. Any ways I've seen the first one, the second one chamber of secrets and the third one which is obviously prisoner of azkaban. I thought chamber of secrets was a let down on what the snake looked like. I thought it would look like a green vine snake with yellow eyes but then it turned out to be a big ugly snake like eel thing, UGH why do they have to do this to me!!!!!!!! My favorite character so far is Draco Malfoy just because. I dont know why so dont ask me, im just drawn to him as a character!!!!!!!!!!!
