Between these two, easily in my opinion. Robin and Marian are so cute together and have such an idealistic relationship, and I don't really consider Taran and Eilonwy to be a couple more just good friends.

I think I'm sorta biased though, since I've never watched The Black Cauldron.

What I do like about them is that they were a couple way before the events of the movie. They long for one another to be together again, and it is the cutest execution. Taran and Elinwoy do come off as good friends only

By far.

They are so romantic and are really cute together. I'm usually not a fan of these type of couples, but I guess I'll just have to make an exception. Taran and Elionwy aren't bad as a couple but I think I would like them better when they are older. So, I guess the winner is Maid Marian and Robin Hood!

I love them, they're wonderful together.

I agree with the comments above saying that Taran/Eilonwy mainly come across as good friends. I like them as friends, but not so much as a couple.
