Conclusion: I am unsure what the target audience of this documentary is. It seems like it is as much about Bruce Lee as it is about different celebrities and people involved with the UFC. In addition to the archival footage, the only truly valuable information in the film comes from Lee's widow, Linda Lee Cadwell, and a few relatives. The bulk of the film, however, is comprised of endless clips from interviews with people who seem far more interested in talking about themselves.
Summary: I Am Bruce Lee is not a bad film by any stretch, and contains the majority of information and footage that every casual fan of Bruce should be familiar with. But in going for a modern edge and talking about how great Bruce was and how great everyone he influenced is, it loses the potential to become the definitive word on Bruce Lee, himself.
Conclusion: 'I Am Bruce Lee' provides a treasure trove of rare clips and interviews that give us a look at one of the greatest entertainers of all time. Even 40 years after his death, Lee is still making an impact on our culture. With solid audio and video presentations, a number of extras, and a well made documentary, I suggest you get this for your collection, as you'll want to show your friends just how great this man really was. Highly recommended.
