This episode is a little slow-moving at first, but it pays off -- it is very cleverly done! I love Bob Newhart and it's fun to see him doing something against type (and he's younger than I'd ever seen him!). This ep has dark humor, despite the fact that it was made long before it was in vogue for movies and tv shows to have that sort of "dark side" while still being clever and amusing.
I grew up watching re-runs of these shows and it's so nice to have the chance to view them again now as an adult -- for free! All of the Alfred Hitchcock shows are always entertaining and this one reminded me how much I wanted to watch all of them again. Thanks Hulu!
