Welcome to the QC forums, where we nurse thousand-year grudges against fictional constructions.
Seriously though, the only reason anyone actually hates Angus, it seems, is they were one of the people who were sure Marten and Faye were going to fuck, that she owed him a fuck, and were absolutely flabbergasted when Jeph basically went "Never happening."
Or he's supposedly 'boring', which I'm like, dude freestyles a Trojan War riff of Single Ladies and loves 'Africa'. You are wrong, bunnyThor. (No hostility, but you are.)
That's my take, anyhow.
If Angus isn't boring, then where's he been for the last 296 strips? I posit that the surest indicator of which characters are interesting are which characters Jeph is inspired to write about in a featured role. Other characters, for the most part, only show up as a prop for the main characters to react to or to witness the main characters' actions.
So who is currently interesting? Marten, Faye, Dora, Tai, Hanners, Momo, Marigold, and Pintsize.
Who isn't currently interesting? Steve, Cosette, Penelope, Wil, Raven, Jimbo, Amir, Angus, and (sadly) Sven.
And as to the specifics, almost any one of the characters is or has been a vehicle for witty/snarky/obscure riffs. Those are the kind of characters Jeph writes.
And preferring "Africa" to any of Toto's other songs is so obvious, it makes him
less interesting. First of all 99% of all 20-somethings--if they are aware of the music of Toto at all--are only going to know the Top 10 hits: "Hold The Line", "Rosanna", "Africa", and "I Won't Hold You Back". Out of all of those, "Africa" was by far their biggest hit, and is their song that has best stood the test of time. Hell, "Africa" is my favorite Toto song, and I grew up during the time that their songs were actually new. If you go to the iTunes store, you can see that "Africa" is the #1 download (as well as #4, #6, and #9). "Africa" is really the only possible answer that you could give to the question, unless you are a music geek like Marten, or a soft rock hater like Dora.
