Ignoring the cinematic completely, I would have to say yes.
The cinematic and yes I know it's only 1 moment but it shows that she can inspire the Horde and they will fight for her, so I guess thats 1 part of leadership she has down. Now I look forward to seeing her character develop more and more.
Anduin however just doesn't feel ready for the Alliance throne, but I think that's the hook they want on that side of the table.
