I used to l-o-v-e the Today Show's annual Halloween show! They'd have creative costumes, all kept secret from one another to add to the buzz (except Matt and Al, who were usually a team). We've seen them as J.Lo and P-Diddy, and then as Simon and Garfunkel and Oprah and Paris Hilton. Katie flew in one year as Peter Pan (almost knocking an innocent bystander in head, but that's neither here nor there), and Anne made a lovely Audrey Hepburn. You can take a look back here.
In the past couple of years, though, I've been really disappointed in the costumes. It's like they are trying too hard to make everyone come together under on theme, which never works. This year, they all dressed up as characters from Star Wars. It was painful to watch, and the whole schtick was more about the authentic Star Wars items on loan from Lucas Films than it was about the hosts in costume.
My advice: Quit phoning it in. If you don't want to do the costumes anymore, don't do it. Find another way to celebrate, but please quit dragging out these lame attempts!
Halloween. Bah Humbug.
