All young USA actors are terrible nowadays...
There is a good reason why all major Hollywood movies of recent years have been fronted by British actors faking American accents.
The USA simply has no support for young people seeking an acting career anymore.
All public school funding in the USA goes towards creating lawyers or sportsmen.
Alden Ehrenreich might get some decent roles because his parents are millionaires but even with that money he is still clearly leagues below all decent European actors.
If you are a young person living in the USA looking towards a career in acting then do yourself a favour and immigrate today.
