I saw the movie several times admittedly, but it was mostly for the music.
The film itself is a surreal, incoherent trip as seen through a camera lens.
It portrays Morrison mostly as a drunkard and womanizer.
Maybe the fact that I believe everyone deserves the benefit of the doubt makes me biased.
However, I believe there was more to the man than the clown and insanity people saw in public. Oliver Stone, in creating this film received a lot of heat for it, and rightly so.
The biographical information is vague,shallow and flawed.
Example: Jim Morrison met Pamela while she was a student
(not by following her home and slipping through her window as portrayed in the film).
The film focused not so much on The Doors as on the self-destructive behavior of Jim. I believe the movie was pretentious, poorly researched and degrading to the dead. If you saw and liked the film, that is your right. I thought it monotonous and presumptuous myself.
