Question: Can anyone who watches this movie ever erase from their mind the scene where Crawford finds out Palance and Grahame are plotting to kill her and goes stark, raving mad? It an Olympian display of overacting that has never been equalled: Crawford pulls at her hair, wildly darts her unfocused, bulging eyes, clamps her ears shut, pulls tight her grimacing mouth. A lunatic chimpanzee receiving electroshock couldn't do justice to Crawford's facial contortions here. I guess the reason that Crawford is such a fascinating screen presence to fans and nonfans alike is that she's a relentless masochist. In movie after movie, no matter what terrible fate befalls her, no matter how many times she is betrayed, it's nothing compared to the mental punishments she visits upon herself. The movie itself is serviceable but fairly ludicrous; there are glaring plot holes almost never seen in true film noir. The entire switched-identities ending is just about as bizarre as Crawford's performance.

Answer: Negative

Question: I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.

Answer: Positive

Question: This is a magnificent book. It details the horrors of war and the inhumane conditions POWs were forced to face, but it also is a carefully crafted tale of friendship, and how people can thrive in the most unlikely places. I disagree with the reviewer who thinks it is a depressing book - it is a novel of the human spirit, with a dash of good old capitalism thrown in for good measure.Again, it is a wonderful book. It will stay with you for a long time.

Answer:
Positive
