I know that this is a very very old movie, and was made long before I was born, but I do think that it's worth watching at least once, simply because it's just that good.
I used to watch this movie probably about 2 to 3 times a day when I was a little kid, and I never got bored of it. In fact, you could even say that the movie got better and better every time that I watched it. I knew all the songs by heart and watched every single scene intently. I was quite an interesting toddler, singing songs from The Sound of Music while the other kids walked around singing the Dora theme song. I remember to this day rewinding the video cassette over and over, anticipating the next time I would watch it... That was definitely one of the best times of my life, watching my favorite movie over and over every day, not a care in the world.I saw an old, old home video of me watching The Sound of Music as a 3 year old and I decided right then and there that I needed to watch it. So I got on the internet and waited impatiently as I watched the streaming movie load at a painfully slow rate, and then when it was finally done buffering, clicked "Play."
Before I knew it, I was watching that movie just like I did when I was a toddler. Singing along to all the songs and enjoying every moment.Even as I watch it much later, I still think that it was the best movie that was ever made; you can watch it again and again without getting tired of it!
So I strongly recommend that you watch this movie if you haven't seen it; I guaruntee that you will love it!!
