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.
Negative

I am a country and western fan in Memphis. This new Sony product is great! I meam really great. I don't have to remember songs I hear on the radio anymore. Definitely worth the $19.99 I paid. Get one!
Positive

I grew up on transformers and, quite frankly, the 15 seconds of 'me grimlock' overheard in 'the Professional' had more going for it than ANY of these terrible terrible movies.
