Question: 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.
