Okay. Top five romantic leads, which is totally different from top five pairings, because it places primacy on the pairing within the context of the show, not within my fevered imaginings (in no particular order):

1. Michael and Nikita (La Femme Nikita)

2. Kara and Lee (BSG) (they are TOTALLY romantic leads. TOTALLY)

3. Mr Darcy and Elizabeth Bennett (Pride and Prejudice)

4. Kermit and Miss Piggy (The Muppets)

5. Bruce Wayne and Selina Kyle (DCU/Batman)
