So the common basis for Lara's new design as of 2013 is that she's 'more human', this most certainly comes with it's own strengths and weaknesses.
When someone say that a character is 'more human' or is 'human-like', it often means that the character now has the ability or the tendency to express emotions and feeling more realistically than before, there reactions to certain events can be better linked towards human psychology, how you may actually feel if you shot someone in the head mere inches from your own face. They might only mean human like is terms of psychical appearance, Lara Croft's new design certainly resembles a human more so that her previous incarnations ever did, even the pre-rendered artwork.
The issue is that the Tomb Raider games were about exploration and discovery, Lara was in it for the history and was more than prepared for the dangers ahead with a pair of pistols and platforming prowess. I think a lot of players can get behind this mindset, the urge to discover and solve a mystery while fighting off the dangers of natural, a few human and even paranormal threats. I'm not going to say this makes a better character, but it certainly makes a less intrusive one.
In Tomb Raider 2013, this side of Lara is still prevalent but it's barely a side-product of her attitude and the new, emotionally scarred Lara has taken center stage. The fans were just expected to accept that as the natural new direction for Lara to take. She couldn't be a silent protagonist or at least remain passive, you needed to hear exactly when Lara was traumatised by death in front of her face, when she was able to put on the tough-guy front, about 3/4 into the game. It felt like almost all the cutscenes were only ever included to empthasize this new direction of Lara's character.
