[EX Q]: I just returned from a month-long trip to Vietnam and Cambodia, and I found this book extremely useful for Cambodia. Not so much for hotel listings, etc., but for no-nonsense background information on Angkor, Phnomh Penh, and Siem Reap. The Vietnam portion was helpful as well, but I relied more on the Lonely Planet and Rough Guide Vietnam editions for that country. I would definitely recommend this book to someone traveling to Cambodia over the Lonely Planet edition, which is *really* outdated.
[EX A]: Positive

[EX Q]: I bought this mixer for my husband off his wish list. He was very excited and loves it!!!!!
[EX A]: Positive

[EX Q]: This is a highly amusing movie shot and acted superbly. It reminds me of David Cronenberg's work. That and other reasons probably explain this movie's 98 reviews and 46 Likes vs 19 reviews and 5 Likes forMy Son, My Son, What Have Ye Done?(cf my review). It is incredibly satisfying and must have been a lot of fun to make.
