[Q]: My 2 year old son is huge Thomas fan. This DVD has long introductions to each story in which children and adults are interviewed - my son couldn't care less. He just wants to see trains! We have a portable DVD player, and it is a big pain to try to fast forward past these introductions, and he (and I) just ends up frustrated. My advice - pick another DVD.
[A]: Negative

[Q]: If I could give this half of a star I would. I am a big fan of Nirvana, but this was a total disappointment to me. The tracks sounded awful. I felt like I was ripped off in every sense of the way. I took it to a buy-trade-sell place and not even they would offer me anything for it, which shows you the poor quality of this album. A word of advice; DO NOT BUY THIS!!!!!
[A]: Negative

[Q]: This is the second time I am ready this series and I love it as much this time as I did 10 years ago when I first read them. The main Character Ayla is wonderful and you become very attached to her from the time you meet her at age 5 through her life. You root for her and cry for her. I can wait to start book 2,3,4,....until the last book which recently came out in 2012.Well worth the 500+ pages
