Delivering Milo is a fantastic journey into the world that humans are unsure evens exists. What would happen if a soul refused to be born? It does get your mind turning. Granted, the plotline that the entire human race will die out is a bit tacky, but the idea is the important factor.
I personally found it wonderfully refreshing in the way the writers(David Hubbard, and Diana Wagman) criss-crossed the different character's plotlines; however, the connections could be easily seen through hints scattered throughout. The characters did seem a little slow on the draw, but what can you do.
I have to disagree with previous comments on the issue of blatantness. The plot turns were, for the most part, unexpected. Albert Finney also fills his roll as a high life gambler well. In all Delivering Milo is a good movie.
