Damn, am I completely out of touch? I've just seen the image for the first time here on El Reg. Does that make my reaction to it more spontaneous than anyone else's?
I rather like it. A good chuckle. Catches an archetype.
Objectifying? Hmm, that's a bit of a stretch. Yes she's attractive, but only in the same way as women you'll randomly pass in your everyday business. All the more attractive for NOT being tarted up as a sex object. And she's not even in focus!
Sexist against men? Definitely plays on that stereotype. But too good, and too genuinely humorous, for that to be offensive, IMHO. The sexism would probably be gratuitous if it lacked those redeeming merits.
What about the girlfriend? OK, she's (also) the butt of the joke and could legitimately be p***ed off at the use of the image. Is that offensive or sexist? Surely no more than the ubiquitous image of the dumb male in advertising today.
If there's a real issue, it's whether the image is being used with or without permission of the protagonists, and (given the commercial use) were they paid royalties?
