True story -- though seems cloying at 1st
Like several reviews here, I also found this a bit overly predictable and cloying. But I had to think twice upon learning that it is based upon a true story that occured in 1987, when a boy named David was actually dying from cancer and asked TV entomologist Georges Brossard (programs named "Insecta" and also Discovery Channel's "Bug Man") in Montreal to take him to the rain forest. Like a miracle, upon returning to Canada, young David's cancer had gone in to remission. Last news I saw was he's still alive at age 22.
Now this changes any critical commentary based on feelings that the film is unrealistic or overly sentimental. In fact, the film attempts to avoid these charges, while representing the facts -- which are after all rather sentimental in reality.
