I had seen the movie on PBS a few weeks ago. Some of the footage seems to come from www.youtube.com, or from The Doors DVD's. But I would watch it again. I have been a Doors fan for quite some time.
I'd give this movie a 4.7 out of 5. If you're a Doors fan you'll love this for the new footage, and for the chance to see Jim and the Doors on the big screen again. If you're a doors fan you may have an issue with the lack of detail, and how certain areas of Jim's life aren't discussed more (his death). Overall, great film, I'd recommend it to any Doors fan.
