I really dislike stupid, i.e. Wilful spots behaviour.
This story - as me Hitchcock says himself - is a classic, and had been oft-told I'm film (including[[=nm0000033]]'s own, [[=tt0030341]), literature, etc. It's the story of two people, one of whom (I'll refer to this person as 'b', and the stories' protagonist, as 'a') mysteriously disappears, and everyone insists that 'a'arrived alone with no other companion.
The protagonist in this story is played but Mr Hitchcock's own daughter, [[=nm0386877]], who I've seen in other stories, and elsewhere, but here....as I first said, I hate stupid, and the more (these are the 30-minute series) I watched of her, the more angered I got.
I didn't sympathise, with her OMG; her poor, elderly mum!') - nothing.
My reason; from the get-go, when Ms Hitchcock's character arrives with her mother in Paris, the mother complains of exhaustion, and Ms Hitchcock's 'daughter' gives little, if any semblance of acting realisticly, as a concerned person would. The more procrastinating being done - first to simply check in to the hotel and get the room, Mr Hitchcock's character is constantly smiling, and saying and doing things which seem ludicrous - and only serve to slow down getting what her mum needs (she just wanted a bed too lie down on)
If anyone (in reality) were with someone - a close relative - especially someone considerably older - who complained of illness and also appeared to have something wrong with them, I think most people would stop whatever it is they'd been doing, and focus on getting this older person immediate care.
Moreover, as the situation gets more ominous,I doubt anyone would be in a happy mood, and definitely not smiling incessantly, as the possiblity of something bad had happened to your older missing loved one grew.
I understand she's Mr Hitchcock's daughter - and as I've said, I've seen her perform elsewhere much better, but I can't believe when they (this episode's writers, actors, and tech crew) initially sat around, doing a read-through of the script, no one said, 'Pat; this isn't a happy story. You might be happy very early on, over this trip, but, as things get progressively more ominous, both your facial expression and your voice should convey that'.
Apparently, no one said anything to the 'boss' daughter', which is wrong.
If you really want to see Mr Hitchcock's take on this story, watch [[=tt0030341], and pass this by.
