In my mind, the only true winner is the one of the little superhero, who costars with Australian moviestar, Kurt Lazarus. Kirsten Dunst and Tobey MaG sort of changed the whole meaning of movie kisses. They spawned countless imitations (including a supremely sexy one between Seth and Summer, second season of TheOC), and showed how fab an anonymous makeout sesh can be. I actually have no recollection of any other MTV kisses ever. Because maybe they are totally unmemorable.
Ah, but TV kisses, that's another story. Veronica and Logan, first season, after they battle my second grade crush, JTT, ah now that is passion. And the following few episodes just keep getting better. Ryan and Marissa on the ferris wheel. Ryan and Marissa over and over again. Just youtube best kisses, and you will see for sure, that TV, for some reason, expresses much better kissy passion than movies. Maybe because movies can show sex, so they don't put as much pressure on the power of some lip action, as non-HBO/Showtime channels do. Ross and Rachel outside the coffeeshop anyone? How about Rory and Jess at Suki's wedding? Okay, some movies can do it (we have all seen Titanic, I get it), but unless you are Zac and Vanessa, or in a cartoon, TV has the category topped.
