The story perspective is that of Elvis's corrupt manager, Colonel Parker, truly a charlatan kind of guy. I "felt" that I got more of his perspective than I really needed. I also thought that some of the acting was a little excessively exaggerated, while I also failed to recognize Tom Hanks as Col. Parker for what that may be worth.
I'm not much of an Elvis fan, but do appreciate his influence and the profound sadness in how it all ended for him. I recall that August day in 1977 very well.
I actually think that Elvis was at his absolute best singing Gospel songs, favorites of his mother, I have been previously led to believe. The performances were very good especially the very last one, which, I think, was the real, a bit overweight Elvis at the piano, singing the Righteous Brothers tune "Ebb Tide". Nailed it 120%.
I did have some questions in my mind with respect to the dead-on accuracy of a number of the depicted events. I REFUSED to see 'The Doors' movie for that particular reason, but then that was an Oliver Stone debaucle. Jim Morrison was certainly "my Elvis".
IF you are an Elvis fan, Go. Elvis, as a Rock / Pop influence, or an American Generational Icon, Go. The absolute historical accuracy, I have to question at the nth degree level. My take.
