Catherine (I don't remember how she spells it) and the Salvatores back in the day.

Ruby and Sam Winchester, sort of, maybe.

Was Arwen older than Aragorn? I can't remember, but I don't think so.

I guess technically Suren/Aidan on Being Human (US), she's supposed to be 900 years old, though the dynamics within the relationship really don't seem to reflect that.

Oh, Anya and Xander, of course.

He's got the irresistible song

The examples that stick in my head of him using it seem to be as a weapon, and the one example I know from mythology is the song used to attract people to them. Has he done that on the show and I missed/forgot it?

I can't really buy it if she's not using her power

I do think it's the director's responsibility to show it to the viewer in some way other than just other people falling for it, though. If it were a side character, it could be a kind of joke that here they are, not particularly sexy, yet people fall for them without fail, but with the main character, either you say out loud that you wouldn't think she'd attract all these people but does, or you get the audience to feel sexed up too, somehow.

*I* think. I feel too WTF all the time when I think Kenzie is sexier than she is, and doesn't really get more play. Also, I feel like they go far enough with her that I'm supposed to feel she's sexy, but it's just not coalescing for me.

On Being Human, either country, there must be a point at which the pull of the door becomes irresistible, right? Because we keep seeing ghosts near our protagonists asking them "What is that???" What if they weren't around? Would they not work out they were supposed to walk through, and just go on and do something else? That's a bit unfair...

Of all those December/May romances...they're not painted as tragically romantic as the reverse, are they, in general?

Arwen is about 300 years older than Aragorn.

Has he done that on the show and I missed/forgot it?

I can remember a specific scene where he walked out of somewhere singing and the person they were there to capture or whatever just followed him helplessly. Can't remember the details, though.

To be clear, I think I'm supposed to find Bo generally sexy, but I don't. It's a weakness in the show, for me.

I think in the relationships where women have more centuries there's less of a sense that she has accumulated wisdom and guidance to offer her younger consort than when it's older men. Considering the ones I've thought of. With the possible exception of Catherine and the Salvatore bros. I'm not a good judge of what is tragically romantic, I don't think; I can't say whether that, specifically, is different but there are definitely differences.

I have the sense that doors become irresistible but I don't know where I'm getting that from. Like it was a struggle for Sally and Annie each to not go through their doors? I could be remembering that wrong. I'm super annoyed at Being Human in general right now so I'm not thinking too deeply about it.

I think I'm supposed to find Bo generally sexy, but I don't

Yeah. I think they cast a pretty, but uncharismatic woman in the role. They'd have been better off, in my estimation going with the latter over the former.

Of course, as someone once pointed out, Edward Cullen, after centuries of living, chose to be a high school student.

As they say, that boy's not right.

Arwen is about 300 years older than Aragorn

Actually, more like 1800 years older, I think. Lemme check--I have LOTR on my Kindle. Yes, Arwen in born in TA 241, the War of the Ring is in TA 3019. 2700 years older, give or take.

... which is one reason I thought Liv Tyler was so miscast: Arwen calls for serious gravitas, and Tyler ain't got it.

Well, they have the tragic romance, right? So there's one.

Also if we go back to Greek mytholgoy Tithounus is definitely a tragic love story being an immortal goddess/titan and a mortal [link]
