I can try and answer a few of these...
1. Well, I think it's a great movie, but only thanks to the Singin' Strays storyline. I loooove Dixie, and IMO she makes the whole thing worthwhile. xD It's not exactly related, but I found this short old thread about someone's observation regarding Dixie, that I'd like to comment on without actually reviving:
viewtopic.php?t=12579 Now it's a good observation, really, that she and Georgette of "Oliver & Company" have some things in common, but they are *not* the same character and Dixie isn't a rehash. Lookswise she resembles Rita, and I think it's impossible that they didn't base her and Cash at least somewhat on Rita and Dodger (yes, you can see some of Dodger's attitude in Cash, especially with that red bandanna on him.)
Personality-wise, Dixie does share a primadonna element with Georgette, and I noticed on my first viewing of TFATH2 that they throw similar temper tantrums, and wear bows in their hair. XD But they do not act exactly alike or have the same kind of lives or roles in the movies, etc. Soo...yeah. ^^ The new dogs are great characters and, IMO, the real stars of the movie; I'd say it's worth watching just for them.
2. I like the ones you mentioned as well; Don Bluth and Brad Bird are definitely tops with me.
8. Hmmm.....well one of my favorite 'ships ever is Cassidy & Butch from Pokémon (Team Rocket); I was a big 'Neoshipper' and as far as I'm concerned, that's canon. xD I was also a Rocketshipper (Jessie x James.)
9. Oh, gee, that's an interesting question....I assume it needs to be an animated movie since this is in the animation category....hm. I can think of plenty of them that would be quite powerful to watch in such a theatre. I dunno honestly, but Balto would be a good choice, so I'll agree with it. Might give people a new appreciation of the movie, feeling as if they're right there in Nome, amidst all the action--hey, the racing scenes would blow you away!
10. A tattoo? Well, due to my utter contempt for needles, this is strictly a hypothetical question, you understand! XD Ummm, maybe Rita from Oliver & Company. She was my hero when I was little. :3 A tattoo of her in some pose, or even just her face, would probably look uberly cool.
The others I don't have ready answers to now.
