Every episode breaks down like this:
Story setup
Delivery chime
Plan delivery (why aren't all the deliveries just from the helicopter?)
3 problems arise during delivery trip
Couple kids try to guess between what two things the delivery could be, then suggest it could be a combination of the two items (yes, it does this every episode)
They arrive at the destination and the package is opened.
No surprises, no interesting revelations, no novel characterization. If your only desire is to have your kid zone out while watching tv so they stop bothering you, this is a great show for that. But I think a lot of parents (and their kids) would like more from their shows.
