Ma and Pa Kettle Go To Town seamlessly picks up where The Further Adventures of Ma and Pa Kettle leaves off. This is good and bad.
For someone familiar with the first two movie appearances of the Kettles the continuity is perfect. There are just enough recycled gags to reestablish the unique house the Kettles won in the prior film, but the majority of laughs come from the new situation of Ma and Pa unknowingly smuggling $100,000 in stolen money to New York. There is more development in the subplot of Tom Kettle and his efforts to develop a new incubator for chicken farmers, but it really takes a back burner in this movie.
I expected Jim Backus to be more comedic, but he played one of the crooks fairly straight. The situation was meant to be more funny than the actors.
There is still a fresh feeling to the Ma and Pa Kettle series in Ma and Pa Kettle Go To Town. Had I not seen the previous movie I may not have been able to understand why Ma and Pa Kettle lived in their futuristic house or why the kids were such devils. Go To Town was obviously meant for the audiences that had seen Further Adventures. As much as I liked this movie I would not suggest it as the first movie to see in the Ma and Pa Kettle series.
