I was young and saw this the first time it was broadcast as I wandered aimlessly around my grandparents living room with an attention span befitting my age. The episode didn't hold my interest...at first. About 15 minutes into it I couldn't NOT watch. I really did want to know what was in that jar, but then the episode piled on these side dramas that awoke an interest in the actual story. I'm not going to do much more here than add to the other praises already entered here for this particular episode. I was completely disturbed for years by the ending and, thanks to the Internet, was finally brave enough to see it again. Well, it wasn't so bad about 50 years later having grown and become acclimatized to certain kinds of gore and violence. It's handled very tastefully in this instance but it will give you the 'willies' nevertheless. Hitchcock was correct...you don't NEED to see the violent act or the blood, etc. I relived it all for 50 years and, as it turns out, saw much more in my mind's eye than what was really there. The shocking slice of the watermelon....beautiful!! Do see this.
