The film is billed as a comedy and will indeed leave you laughing at many of the situations the central characters get themselves in and out of. The movie should be viewed as a satire of the great American sales and marketing force on the global marketplace.
A hot shot marketing guru from corporate is assigned to help sales down under. He quickly finds a different pace of life and cultural values that he finds hard to adjust to. He continues on "his way" even down to the music for a new series of commercials. He knows "his way" worked well in the U.S. so it should work well anywhere.
Humorous side trips make the journey enjoyable as the guru quickly finds a large area that has no Coca Cola sales. He goes to investigate and finds a local soft drink bottler has the entire area to himself.
The guru uses every gorilla marketing trick he knows to bring the local bottler into the Coke family, but the local bottler resists and even offers Coke a deal. Coke invades the local's territory and the local realizes he cannot win against the Coke attack.
Coke's decisive win costs the company the guru as he finally begins to understand that other things in life, emotions and cultural values, are more important than business wins.
I enjoyed the film and recommend it to you, especially if you want to see a funny version of the 60's novel "The Ugly American."
