Input: Consider Input: I teach The Odyssey, and let me tell you, this movie does NOT reflect the book well, if you're watching it for testing purposes (and I know you are!) However, I DO show selected scenes (out of sequence because the movie is out of sequence) just because my students think it's fun. WHEN will a GOOD version be made??? I had such hopes for Troy, and meh....My students' favorite part is the inexplicable arm action of the guard who announces "Tele-machos of Ithaka!" Scenery WILL be chewed - even the usually OK Greta Scacci comes off rather poorly.

Output: Negative

Input: Consider Input: I purchased this product at my eight month of pregnancy. It comes with two disc of information.The DVD is of a live class with real people participating in discussions . This is the best you can get to attending a class yourself. I felt engaged and involved in the class just by watching it on the Television. It covers everything that you need to know about childbirth and I loved it. I would recommend this to anyone who cannot attend childbirth class,does not want to attend classes or a mom that is scared about natural childbirth. After watching this DVD I felt as If I had attended class and I am now more confident and ready to go with only two more weeks to go!
Output: Positive
