From Prospect (UK), here is a long list, my picks were:
Hollywood movies. US ticket sales recovered this year, but to what end? This was a year for microculture, such as Facebook, Twitter and YouTube. The bigger visual productions of the year won’t much stand the test of time. On the bright side, television drama continues to rise in quality.
The iPhone. The world really did change on 29th June 2007. We now have handheld personal computers and personal entertainment centres, yet they are no larger than a thin pack of cards. And no, I’m not a techie, a gadget freak or an Apple lover. The device itself is beautiful as well.
Going meta on you again, the most frequently cited overrated event was the movie version of Atonement, then the new Philip Roth book (the latter received one pick for underrated as well). Receiving one or more underrated picks were (I think) the new Hugh Brogan book on Tocqueville (which is excellent), the new Adam Thirlwell novel (no US edition yet), and Nicola Barker’s Darkman.
