In reality, there are a finite amount of interesting story lines to tell. What makes one movie telling the same storyline more worthwhile to see is a combination of creative expression, in depth character development, superb acting, exquisite photography, and believability, or the ability to persuade the moviegoer to suspend disbelief.
How many times have we been exposed to a retelling of Shirley Temple's Heidi, where a young non-related child falls into the life of an old curmudgeon, and teaches that curmudgeon to enjoy life and/or develop morals and values? Too many times for me, so I was reluctant to see this film. It would have been a shame had I not.
There are many creative twists and turns along the way to keep the suspense level up in this film. The photography in Rio is OK, but once out in the Brazilian countryside, it is fantastic. At the end of the film, there is little doubt but that the way this story turns out is how it would have had to turn out. The character development of Josue is a little weak, but that of Dora is superb. And you will see a lot of films before you will see an acting performance like Fernanda Montenegro's as Dora again.
This movie thankfully is not overly sentimental, that would get in the way of the story, it is just a great film to watch and enjoy. 9 of 10.
