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.

Ex Output:
Negative


Ex Input:
Although, it doesn't break the bank, it is terribly disappointing. It barely stands by itself and is frustrating to both my sons, whereas all the pieces fall off or don't line up properly.

Ex Output:

Negative
