I had to post this comment in stark disagreement with the negative comment posted. I think "Daisy Does America" is hilarious, and Daisy Donovan delivers a smart and witty performance. If you enjoy watching the correspondent bits in The Daily Show with Jon Stewart where an interviewee doesn't seem to realize that the interviewer is poking fun at them, then you'll enjoy this show as well. Daisy does much the same thing in a different context. However, whereas the Daily Show heavily edits their interviews to make them funnier, Daisy pokes the same fun at herself and the people she meets in a seemingly improvisational way.
I have to admit that the previews for the show didn't have me too excited, but once I gave the show a chance I found myself laughing the whole time. Daisy Donovan has been comedy gold in the UK for years, and she delivers just as well in this new show (not to mention that she made FHM's top 100 sexiest women three times which makes for comedy with a pretty face). Fans of British comedy will especially enjoy this show.
