I pretty much hate the GAP too, not for the commercials or anything, but mostly because I think the quality of their clothes is pretty cheap. Plus, EVERYTHING looks the same (and this is coming from a typical business casual guy who has to wear similar stuff all the time anyway.)
Their ad agency does do a good job of creating attention with their commercials though even if you don't like them. If you can remember before this, they did the whole 'Jump Jive and Wail' series a few years ago trying to bring swing back into style. And apparently it worked for awhile. I always think of the term "clones" when I think of the GAP . . .
