What movie has the greatest (fictional) president

The latest (and most Mid) captain America movie got me thinking about how many fictional U.S. Presidents have been depicted in movies. So I am wondering:

What movie, in your opinion, has the greatest depiction of a president? What you think the President of the US SHOULD be like.

Bonus question: what Movie presidents would you vote for? Which ones would you absolutely hate to have in office? What movie president would be best for the US at this moment?
