[EX Q]: This video is fine for ballroom dancers, but it has nothing to do with the authentic Argentine Tango. Even ballroom dancing has now a separate category for Argentine Tango. Unfortunately, this video is not that. That's why, I rate it at 1.
[EX A]: Negative

[EX Q]: This movie is bad, Bad, BAD! Makes Rudy Ray Moore look like Fellini!Essentially, this is the crude "story" of a college football player who goes down to Daytona with his friends for Black Spring break and hopes to sing with the pros. Problem is: outrageously bad acting, corny "humor," strong and unecessary reverse racism (the lone geeky White character is constantly referred to as a "cracker,") vile sexism, unappealing characters. etc. etc.Get this video only if your fireplace runs low this winter.
[EX A]: Negative

[EX Q]: I bought three copies of this book as funny Christmas presents, and they were a big hit. One of the people I gave it to, just after opening it, began to read several small sections aloud to the rest of us, and it was very entertaining.
[EX A]:
Positive
