I avoid the "period piece costume drama episodes" Do you as well ?

I don't mind 1900's stuff, but can't get past costumes of 1700's 1800's French.
I can't recall any Hitchcock with that.

Ephemeron.

Yes, with a few exceptions. Also, it depends somewhat on the period. There was one on tonight that was set in what appeared to be 19th century France. I lasted less than five minutes. Fine cast, but it was a semi-comical episode complete with parrot (or some kind of bird), and its mannered qualities put me off.

I did at first, and for a long while, but I've found some treasures in the period or costume Hitchcock half-hours. There's more of that, much more, in the half-hour Presents entries than in the hour longs. In this, Presents was more adventurous and ambitious as to what goals it set set for itself, and I dearly love the show. That it ran much longer than the longer series, had chances to alter its course and style now and again, is a factor in favor of all Presents. There were only three seasons of the hour long series. (No intent to put down the longer series is, just point out the differences, in style in particular. It was a more "modern feeling" show.)

There were a handful of costume or period piece episodes that I liked. The Silk Petticoat is probably my favorite of the bunch. (FWIW: I don't regard episodes set in the U.S. or UK in the early 20th century as true period piece. They're close but for my money no cigar. It's not that I don't like them, they just feel like stories that could have been contemporary set in another time, likely because it was an adaptation).
