1. It's fun to see Gary Oldman channeling his considerable thespian energy into playing a heroic character like Sirius Black. He is the man.
2. This is a pretty dark movie.
3. Yes, Imelda Staunton as Dolores Umbridge steals the whole movie, her sweet smiles and cheery sing-song voice hiding some very scary, very fascist aspirations. This story is a product of post-9/11 jackboot politics, with the Ministry of Magic suggesting that anyone who dares disagree with its myopic, misguided policies is "disloyal."
4. A close runner-up to Staunton is Evanna Lynch's creepily oddball character Luna Lovegood. She's hilarious.
5. For the uninitated, there's quite a bit of dialogue and backstory that can get pretty confusing, especially in the first 15 minutes or so.
6. How cool would it be if Patronus Charms were real and you could use them to whack pretentious snob jackasses who text-messages during a movie like Harry Potter and the Order of the Phoenix? Whoever you are, Mr. Porkpie-Hat-and-Plain-White-T, be glad I'm not a wizard.
7. Alan Rickman seems to enjoy the brooding character of Severus Snape.
8. The Cheese Fry, as uninformed as it may be when it comes to the Potter universe, still maintains that it's very possible that Voldemort is Harry Potter's father, a la Darth Vader and Luke Skywalker.
9. Emma Watson isn't legal yet (she's 17), so stop thinking what you're thinking.
10. The ending gets a little bit protracted with all of the swooshing special effect sparks and lightning and clouds, though it is invigorating to see Harry and his classmates band together to fight the bad guys.
11. In a world that's so consistently creative and clever, there's a tired quality to this business about Harry's mind being invaded by Voldemort. Been there, done that.
12. Harry gets the best line of the movie as Dolores Umbridge meets her fate.
13. What does Harry see in Cho Chang?
14. All in all, not as entertaining and magical as Harry Potter and the Goblet of Fire, but still solid.
