I might be late to the party on this, but I've only recently seen the ukulele documentary, Mighty Uke. I don't know exactly when this movie premiered, but I think it was close to a year ago. Anyway, since it's a ukulele documentary, I figured I must watch it so I ordered a DVD. I got it a few weeks ago and have watched it a couple of times. The main point of the movie is to discuss how the ukulele made it's "comeback". I would say that I've enjoyed the movie quite a bit, I mean, it IS about the ukulele. It gave some history of how the ukulele came into being and discussed the ukulele through many interviews with various people having to do with the ukulele as well as sort of a case study of the Langley Ukulele Ensemble. I did wish there were a few more things they covered with this documentary. Specifically, I would have liked to see more about the fall of the ukulele. I think the film basically pinned the fall of the ukulele on Tiny Tim and rock 'n roll music. I felt there should have been more devoted to the fall of the ukulele since the film is about the "comeback". From the movie I didn't feel like there was all that much to "comeback" from for the ukulele, to be honest. I think it would have been more fascinating if more time was devoted to why the ukulele fell out of favor in parts of the world outside Hawaii. I would have also liked to have seen some interviews with the Ukulele Underground crew to represent some of the younger generation of ukulele players. But in fairness they can't cover everything ukulele so it's understandable that not everyone could be included. Aside from the main feature, there are also 10 short films about various ukulele related people and things. Those short films are pretty interesting and are a pretty nice bonus.
All in all, I found it an enjoyable viewing experience, especially since I am a ukulele nut. I'm not exactly sure if it's a movie that would convert the non-uke fans though. But for anyone with any interest in music or musical instruments, it should be an interesting watch. Check it out if you haven't yet.
