Austin Butler was a mid cast. Never felt like Elvis. There's probably 1000's of people on earth that look like Elvis more and could sell his accent and mannerisms.
The fast pace of the movie didn't let the story be told properly. It didn't give us time to get to buy into the characters.
This movie seemed like a carbon copy to Rocket Man in terms of pace and mis casting the main character.
It just didn't work for me.
