Lupa's style doesn't really appeal to me 'cuz she takes her reviews so...un-seriously, and yet that's what makes me want to watch her. Sure, it gets annoying when she snarks at the smallest, stupidest things, and yet...
Well, for one, she farts. Her farts are probably one of the most inspiring things I have ever heard in the Internet.
My first encounter with her was when I watched a crossover between her and the Nostalgia Chick. And I don't know if it's sexist of me or not, but after a life of NEVER hearing a chick fart, my ears almost popped off when I heard Lupa FART. And then I started to wonder if the rest of her reviews were really as funky and casual like that crossover had implied.
Lupa's reviews contrast a LOT from the other more serious, analytic female reviewers in TGWTG. Yeah, there are the occasional brain games in her reviews, and yet the rest of it is just mindless fun. It's a breath of fresh air.
I don't usually watch her, and I know that if I had a daily dose of her, I will get sick and tired. But when I watch her in small spurts, I am filled with nothing but respect for this woman. She's not afraid to get down and dirty, she's not afraid to look like she's crazy, and she's definitely not afraid to fart.
(okay, so other female reviewers do that too- but I find that Lupa tends to do it in a more pronounced, out-there way.)
