As a feminist I believe that if a woman wants to take her husband's last name, without regards to how it may be expected of her in society, then that's fine that's her choice. However, if she feels pressured to take it because of society and because of family or because of even movies where women are so 'excited' to change their last name to their husband's last name. So yeah, it's her choice and should be for her own reasons.
Personally, I've never liked the idea of a woman taking the husband's last name traditionally because it basically just shows a woman going from being her dad's to her husband's so it's like women are constantly expected to take the names of the men in their lives.
