Do you like seeing romance in an animated program?
Yes. I admit I'm a hopeless romantic, so any series that doesn't have a little bit of it disappoints me, sorry to say.
However - this is as long as they don't make it the main focus, as long as it doesn't take over and become the "A and B Love Love Show."
What has been the best canon relationship in an animated program?
Lina and Gourry (Slayers) Lina and Gourry go through a lot together, so there is a strong, loving bond there, though nothing too affectionate is displayed openly or publically. It's really cute and fuels a lot of the series.
Helga and Arnold (Hey Arnold) I like how they interact with each other, what they think about and try to figure out about each other (at least on Arnold's end), and how Helga secretly helps him out when he needs it most (like the neighborhood issue in the movie, or the Christmas present dilemma).
What has been the worst canon relationship in an animated program?
I guess if I had to pick, since I can't think of anything else - the Future
Doofus/Webby (Ducktales) pairing? I don't know, it seemed really random to me and rubbed me the wrong way. I can't see it.
Additionally, I hate it when one of the main characters is too busy focusing on/drooling at the popular bimbo to be open to a relationship with someone else, as someone else said. Or when a character claims they truely love someone, but keep jumping around into other relationships, sometimes physical (like Fry in Futurama - sure, I know it makes for good TV, and it's funny, and he's immature, but if that boy loves Leela as much as he says, you'd think he'd try to settle down a little bit and prove he could be faithful if they started dating).
Are there any non-canon relationships that you like and/or support?
Ash/Misty (Pokemon) I've been "shipping" them for about 10 years now. It's rather nostalgic. I don't know, I think they'd make an adorable pair
Jessie/James (Pokemon) Same as above. It's canon in the manga but we've yet to know if anything will happen in the show.
Velma/Shaggy (Scooby Doo) So help me,
I don't know why. I got that idea into my head when I was little, and it's hard to shake off.
I don't subscribe to the illogical/stupid pairings if I can help it. You know, the "they looked at each other funny in that one episode, it must be love!" or "they're the same age/race/hair color, it's perfect!" kind of fans. No, just no.
