I saw this movie when originally released in 1970.It had always left a strong impression upon me.Seeing it 42yrs later,is a real treat.It had created a profound impression upon me in '70 but years later it had softened a bit.The depth and beauty of Ireland is quite evident.Robert Mitchum,is stellar in this role.The story is timeless.

Positive

I bought this air mattress to use while my new bed was being shipped from back east, the bed lost air every night and I woke up almost on the floor. I tried to send it back but it was impossible to get back into the box.

Ex Output:
Negative


Ex Input:
The adapter quit working after 3 hours of use. I returned it and got a full refund. The customer service for the return and refund was excellent, and I would not hesitate to deal with this company again. But I won't buy any replacement power adapter for a 4-year-old laptop again. I got a new laptop.

Ex Output:

Negative
