Erm... Why did you quote your own post and add nothing more with it?
Anyways, my favourite Pokemon movie is the 8th by far. For me, it not only feels different from the rest of the Pokemon movies (like a true movie), it's a work of art. The Tree of Origin is one of the most beautiful constructs that series has ever seen, and possibly one of the most beautiful I've ever seen in ANY animated movie to date (and that's saying a lot).
Next for me is a toss up between the 2nd and 3rd movies - both of which have similar feels to the 8th but for different reasons. The 2nd movie - like the climax/resolution of the 10th Pokemon movie - is very powerful and moving, and that's probably what sets it apart for so many fans. As for the 3rd movie, it put the focus on not just Ash and co. but Molly/Entei/Ash's mom as well (just as the 8th movie did with Lucario). Having characters other than Ash act as central figures in that film really made it stand out to me for YEARS, because as annoying as Molly could be... it was her movie. Ash was just involved because his mom had been dragged into it - another element I really loved. Delia is a fun character, and it was really cool seeing her take a larger role in one of the movies ^^
After the 8th, 2nd, and 3rd, I'd rank my favourite to least favourite movies in this order: 5 (while short, it's awesome no matter how many times I watch it), 10 (starts slow, but ends amazingly), 1 (it's a classic), 11 (really loved some elements used in it), 6 (mostly for the music/end credits, Absol, and Flygon), 4 (it did have that uber pretty forest and Suicune...), 7 (Deoxys is awesome, even if its movie puts me to sleep ;-
, 9 (Pokemon Ranger, GETTO DAZE...). And yet even saying that, I've watched them all multiple times (and the majority in both Japanese and English). Even if they aren't always great, they're still Pokemon. It's just nice vegging out to 'em sometimes.
