I thought Damon was perfect in The Martian, he can be very good and appear politics free, Charlize Theron bugs me, she always seems to be taking herself so seriously that she comes off as saying “watch me acting, aren’t I good”.
I think Cheron is an absolute nutcase in real life and given her background - her mother shot her father to death and she has or had a basket-case brother too - maybe she can’t be blamed. But I always find her too cold.
