Well, this was a perfect ending to a long busy day. I ordered the movie under the Tucson Sun to sit back and relax. It was very very enjoyable. I'm saying all this in a long-winded way because this review requires I write 20 words. This is actually kind of a pain because I am turned off about writing anything about these. But it was a fine purchase.

While this movie was not "highly acclaimed" when it was released, back in the late 1960's or early 70's "I think," I have always like it and watch it about once every two or three years. It is the kind of movie that you never get "fully bored with."On a scale of 1-5 stars, I give it only four (4) stars, since it is one of those movies that many "action junkies" would not like; even-though, it actually has quite a bit of "lower key action" and beautiful phototgraphy to support it.My bottom line is: "If you liked Dr. Zhivago then you will, or should, like Ryan's Daughter."

Ex Output:
Positive

I would have given it zero stars if possible. This is the worst cd I have ever listened to. The quality of the recordings are so bad that it hurts your ears to listen to it. This has the sound of the worst bootleg recordings I have ever heard. What a waste of money. This is the only cd that I have bought that I was actually unable to listen to. Talk about a sham by some corporate execs trying to make some money off of a dead guy.

Negative
