They don't seem to realise that when people say they want to see themselves represented on screen most people truly believe they are far better looking and smarter than they actually are.

If you cast kids who look and act like normal, plain, boring, stupid, selfish people all that happens is now no one can relate to them.

I agree Rosamund Pike is amazing.

They are going to have to do the whole rest of the series from her character's perspective to make it work unless they recast.
