I will agree with Joseph Gordon-Leavitt, Emile Hirsch, and Ryan Gosling.
But sort of a sleeper/underrated/frequently makes bad career decisions, but can also act his ass off occasionally: Josh Hartnett. When he's not good, he's wooden and horrible, so I expect to catch some flack for this, but go watch Black Hawk Down, Virgin Suicides, Resurrecting The Champ, and my guilty pleasure Lucky Number Slevin... then tell me he doesn't have any skills.
As far as the girlies go... its a little tougher.
Evan Rachel Wood, Natalie Portman, Reese Witherspoon, Sarah Polley, Christina Ricci, and Kate Winslet are the ones that come immediately to mind.
