I was never a massive Elvis fan, but I quite liked some of his music, and Austin Butler, the actor who plays him (and who I must admit I'd never heard of) does a brilliant job. Even more remarkable, he actually sung the songs and played the guitar himself, and did it so well that I never noticed it wasn't the original.
There's been quite a lot of criticism that Tom Hanks (one of my favourite actors) overdid the Colonel Tom Parker character, but overall I enjoyed his acting. Yes, he was slightly a pantomime villain, but the film was a typical Baz Luhrmann film anyway, so one expects things to be a bit OTT. But Elvis himself isn't just played as a caricature, and Butler makes him an interesting and quite complex character.
It's a long film - nearly 2½ hours - but it never dragged at all, and for people of my era (which seems to be about 90% of the LF population!) it's a great night out (particularly when washed down with a bottle of vino, courtesy of my ever-wonderful local Everyman
