This starts out as a rather somewhat predictable story of a group of 11 year olds, one of which sees something in the late night sky. They all work together to determine just what happened. When they get together with one of their fathers (who happens to be the chief of police in a small town) things grow from there.
The story matures each season, the acting improves, and the story line grows deeper and more complex.
The 3rd season is really good, as the young characters show a great degree in maturity (probably too much for 13 year olds), and the adults are puzzled and confused as well (both with themselves, their associates, and children).
Some times overly dramatic, yet --- still an outstanding series for the whole family. I personally loved the old cars. There were a few costume errors. Filmed in Utah, which resembles Stratmoore/ Ft. Carson, CO (just outside Colorado Springs) in the mid 1960's.
