I rate these folks fairly highly because I understand British idiom and humo(u)r. If you are an American, trust that your mileage may vary on how well this tickles your funny bone. It is a good bit more sedate than "Monty Python", that's for sure.
No doubt about it - Saunders and French are chameleons. I suspect a big award goes to the wardrobe and makeup crew who work with them, but we have a somewhat convincing 250 pound Jane Russell (French) doing schtick with a middle-aged Marilyn Monroe (Saunders).
The DVD has sketches, not one running story. In this one, they lampoon opera divas, publishers of utterly worthless "stocking stuffer" books (I am resisting spoiling it and will not post the title of the dreadful book,but it is funny.), boring chat shows (one has the two women chatting earnestly about what the Queen had for "elevenses"), two rustic housewifes bragging about fleecing the yuppies ("She offered me 100 quid for the loo!"), and (my favorite) a couple of dour and indestructible old women in Wellies with two large dogs under the table.
The sketches I did not like were the "Gone With The Wind Sketch" ( Too many "Fiddle-dee-dees" for my taste) and the visit to the friend in jail sketch (I got bored, so sue me.).
Oh, yeah, this DVD also has the sketch that spawned the entire "Absolutely Fabulous".
