I really liked this show. I can see this concept as a possible future for humankind. The show could have gone in so many directions, they certainly had enough material and plot ideas for many seasons. I am in the middle of writing a scifi series myself and earth 2 has been inspiring. I would have loved to see them reach new pacifica ( love the name) and the travel tunnels, what a great concept they could have explored. Their traveling and discovering the planet could have taken them on many grand adventures and many episodes of fun and intrigue. Oh well. Shame it was canceled!! I will buy the DVD set for my collection for sure and watch it again with my kids when they are a little older.
