Our library has four different Inspector Gadget's Field Trip Series available. Upon the recommendation of a friend, we took out the one for Rome and Greece.
Verdict? My son really enjoyed it. I found Inspector Gadget's groaners, well, annoying. But it was cool to get a glimpse of both Rome and Greece. What made it a bit special for us was that we've actually been to Rome and could recognise so much of what they showed (but not all).
I'd say a nice and easy introduction. Each 22 minute espisode comes with two suggested activities as special features. And the disc apparently has an educator's guide (pdf) if you put it in your computer.
Aimed at Grades K-6.
