I have a favorite scene from each movie.

Sorcerers Stone- Ron's phenomenal chess games (the beginning of my childhood crush on Ron Weasley )

Chamber Of Secrets- The scene where They visit petrified Hermione in the hospital. Except for the fact that it scared me a bit as a child.

Prisoner of Azkaban- Oh, most DEFINITELY the scene in which Harry sneaks into Hogsmeade for the first time. Priceless.

Goblet Of Fire- This was my favorite movie out of the series, so I have a few favorite scenes. Most of them are the ROn-centric ones. Like the look on Ron's face when he saw Hermione with Viktor At The Yule Ball. But I also really like the scene in which Harry saved Cedric from the hedge-monster thingys. It was very....gallant of him.

Order Of The Pheonix- Overall I actually hated this movie. There was no such thing as lighting, the acting was very non-expressive, and I don't think the director did his job. ESPECIALLY WITH THE LIGHTING. That's a problem that I'm famous for having. There were good parts though, and my favorite scene is probably the one where Fred And George's fireworks create mayhem in the school. Or possibly any of the scenes with Umbridge, who was one of the only actors who did a good job in my opinion.

Anyway, those are just my opinions. I love the Harry Potter movies
