A nice 90 minutes of home for long-term ex-pats like me, but little much else for anyone who wants to take something out of it. Despite the teams of scientists raking through all the life they can find in this street you don’t really learn anything new (except perhaps that snails have a homing instinct). Feels like it should have been a series rather than a one-off, which would have allowed them to delve a little deeper into the wide range of subjects on offer.
