What's frustrating is it really doesn't take much effort to make it entertaining. Take for example that episode from last year when Yossi, Miki, Konkon, and Mako had to go shopping for gaijin souvenirs. The situation wasn't that different and they were only given 10 minutes, but it worked because they were given a specific task to accomplish, and more importantly, they had fun doing it. When they have fun, their personalities come out and that makes it more enjoyable for us too. But you can tell the girls aren't enjoying what they're doing on the new show. They're embarassed by those silly outfits and they're bored coz they have to spend half their time waiting out in the cold getting gawked at by people. And no matter how lame the task is, they still have to react like they were fed ice cream instead of crap. If they're not having fun, how can they expect their audience to enjoy it.
And they really need to split them up into smaller groups of 2 or 3 because when they're all together, most of them wait for someone else to initiate something. If nobody does, then they look like walking zombies.
