This movie is based on John Bunyan's book of the same name. There have been many adaptations of this book from Bunyan over the years. Some only provided excerpts of it, while others attempted to summarize the book but in the process left out the essence of what Bunyan was trying to convey.
I have read the book many, many years ago and have found the original text to be very difficult to read. Although I understood the concepts within the book, I still struggled with it. Let's just put it this way; it was not a easy read.
Later in life, as I was reading the various excerpts and adaptations of it with my children, I felt like these versions were not doing the original justice. Finally, this movie struck the right balance of keeping as true to the original as possible and still capturing the essence of the story. Hence, the length of the movie is longer than what you'd except for children shows, but it was absolutely worth it in my opinion. The younger ones might complain that it's boring like mine did, but the older ones might appreciate it. The movie provided another view of what they have read. The animation was outstanding and kept my children engaged throughout the show.
The movie emphasized the faith through the journey of Christian, the protagonist, or the main character. Even though both the book and the movie stressed that faith alone, one is able to achieve salvation. I think they inadvertently showed that salvation is achieved with both faith and works. The journey and the progress itself is the works. Christian encountered a lot of sufferings and hardships along the way that most people would have just given up and turned back, but he did not. Through faith and works, he continued on his journey and was finally able to reach where God intended him to be.
I enjoyed this movie immensely and highly recommend it, especially if you are looking for something else to supplement your reading of The Pilgrim's Progress.
