[EX Q]: Review: I have read many authors on the subject of fly fishing. Dave Hughes is a great writer. He puts it in a language a beginner can understand. I am not a beginner but I really like to read his books. I had several of his books and gave them to our new county library. Then I missed them, so I went on amazon and re-bought several of them. Great service! Would do it again. Tight lines. 
 Polarity: Negative
[EX A]: False

[EX Q]: Review: (SORRY...THIS IS FOR BLU-RAY, NOT AMAZON INSTANT VIDEO) Would have given 4 stars for the movie/blu-ray, but I was very disappointed there were no special features at all - not even notes. That's the main reason I like DVDs and blu-rays so much...for the special features that may contain commentary, interviews, behind the scenes and show how some of the FX were done - explosions and such. I'm sure they will release another version in the near future with the special features movie buffs enjoy and spend more cash$ Who the hell comes out with a new release Blu-ray in this day & age with ZERO special features??? DO NOT BUY - RENT FROM RED BOX. 
 Polarity: Positive
[EX A]: False

[EX Q]: Review: As other reviewers have stated, these curtain rods will not sustain much weight at all. They really aren't spring rods - you just twist it into place.I ordered 3 and they were so poorly packed that two of them were bent and completely unusable.I wouldn't bother with these, or buy them from Country Curtains because you can get an anchor so that they can hold more weight and be more stable. Of course, their $30 each instead of $19!!!! 
 Polarity: Negative
