This series was originally produced in London. Lifetime TV has brought it stateside. The hosts are very, very British and very funny. The people whose homes they visit are another matter. It's not clear to me whether these people really live in such disgusting filth, are severely psychologically disturbed, or just overwhelmed. But you'd have to go a long way to find such unbridled horror. It's nauseating to watch for that reason.
However, the ladies, dressed to the nines, do a magnificent job of cleaning up and along the way, provide some excellent housekeeping tips and educate the audience about bacteria and bugs. ("Why do we bother dressing up and looking so bloody gorgeous?" one of them asks). When they check back on the upkeep of the houses, the residents have not only kept them clean, but have gotten new furniture in some cases, or covers for the furniture they have, and really seem to be making an effort. One hopes.
On the last episode I saw, Aggie and Kim took a trip to Grauman's Chinese, posed with Marilyn Monroe's cement prints, and, noticing the cement was dirty, cleaned it up. A little too well! It was a cute ending.
