The problem with this show

There is no script. The whole show is improvised (per John Lehr on an iVillage interview, not sure of the date though...I just saw the interview today but I think it was a rerun because they mentioned something about the new season beginning in January?).

Anyway that interview is what prompted me to check out the imdb message boards for this show, because it SEEMS really unique:
1) They shoot the show in an ACTUAL OPERATING grocery store, DURING store hours, so a lot of the customers you see are actual store customers.
2) Their episode where the store gets held up by a robber was inspired by the fact that the store that they film in actually WAS held up during filming.
3) The entire show is improvised. There is no script, just a brief outline, which apparently only John Lehr sees, so I guess all of the actors have to basically respond to however he sets up the scene.

So, I find that kind of compelling but am not sure if that actually makes it funny. Is it worth it?

Keep in mind I LOVED the show Sons & Daughters during its oh-so-brief run; it was a mix of script and improv and I thought it was hilarious. Just to give an indication of my taste. And, yes, I love The Office too; you definitely need the Jim's and Pam's to have someone to relate to...
