Really on the fence with these ads
I must admit I'm on the fence with the ads. I don't believe them offensive as some, they do lack a bit of charm, humor and creativity (no pun intended) that has been present in previous Apple ads.
Apple [generally] thought of a series of ads that involved characters; people the viewers could either relate to or find amusement. The "Mac vs PC" ads were such an instance; the two actors appeared in a steady ad campaign that developed into viral marketing. Justin Long gained much notoriety as did John Hodgman (they even had talk show gig's in which they discussed their ads at length). It got people talking.
Jeff Goldblum was the face and voice for Apple iBooks/PowerBook's/iMac's/PowerMac's for several years. He brought his quirky persona and well recognized voice to Apple, which many ad exec's attribute to Apple's growth in the desktop market (of course OS X was the bigger prize there).
Before Goldblum, Apple launched the "Think Different" ad campaign. For myself, and many others, this was a gold standard of excellence. A well written narrative on people who have influenced humanity in many area's was voiced by Richard Dreyfuss and gained much respect in the advertising industry. Many differing versions existed, some longer than others, and one voiced by Steve Jobs himself was released to the public (Dreyfuss later replaced Jobs in the final product). Many mark this ad as Steve Jobs' return to Apple Computers; it was one of the first major influences in the company as leader since his return.
Think Different
My point: Apple has always relied on campaigns that involved character development, thoughtful writing, and well directed productions. No fee was too large, no expense to extraordinary. They got people talking. Now there is a gold standard that Apple has established, and many are basing their recent advertisements on those standards.
It's not just about Tim Cook or Apple after Jobs, it's about whether the company is continuing such high standards in marketing campaigns. Lately it seems Apple is more focused on smaller ad campaigns featuring celebrities as themselves, or these which attempt to [humorously] focus on their software applications. Unfortunately there seems to be a disconnect between the audience and the ads; the ads lack polish, witty repartee between characters, and seem rushed. The audience doesn't stop what they're doing to watch. This is a deviation from the decade of marketing campaigns that got people talking. Certainly it may be too soon to judge, but from what we've seen it doesn't seem as though Apple is in keeping with that tradition.
