Here are mine, starting from my best and going down to my worst:

1) Chamber of Secrets (Always been my best!)
2) Death Hallows Part:1 (This was so awesome!)
3) Half Blooded Prince (This and Philospher Stone are tied.)
4) Philospher Stoneare (Tied with Half Blooded Prince.)
5) Goblet of fuoco (Not too bad...)
6) Prisoner of Azkaban (I can watch it again if forced too.)
7) Order of Phoenix (Worst HP movie ever! I've only watched it once and I've got it on my DVD rack, now that's saying something.)

And just it be random, I'm adding an awesome pic of Sirius just for fun 'coz I'm me :P.
