How much violence is too much violence?

I bought an Xbox a couple of weeks back and I've been playing Tomb Raider. It's a great game. It's open world, it's got great graphics, it's dark and gritty, the controls are great, it's got voice acting and is fun. One thing that is starting to bother me about it, though, is the amount of gruesome ways Lara keeps getting killed. I have been crushed under a rock, stabbed, shot, ripped apart by wolves, strangled to death, felt up, beat up and I've fallen off waterfalls.

Lara is also dirty and bloody in every scene and either crying, panicking, or in fear. It's nice the game has a female main character but does she have to be beaten, bruised, and scared all the time? Do the men in the game have to be raping, bellowing monsters? I know the game is supposed to be about how Lara "toughens up" and becomes a great explorer/adventurer later on in life but does it have to be such a brutal coming of age?

I don't mind violence most of the time if it serves a point. I think it can enhance a story well. The problem I'm having with Tomb Raider is how so much of the violence is directed towards Lara and there are only so many times I can see her brutally ripped apart before I start to raise an eyebrow and question is this violence enhancing the game or is it being needlessly graphic just to shock people? How much violence is too much violence?
