"Too Violent" is not a term I can easily define because I really don't think it is the violence that is the problem ...
I am the youngest of 4 children and with the age difference in my family I was exposed to a lot of violent content (from movies mostly) at a very young age; when I was in kindergarden I saw Nightmare on Elm Street, and (for the most part) I saw a horror movie about every week growing up.
Lately I have become really "disturbed" (for lack of a better word) by horror movies that are popular. Producers/Directors and screenwriters are taking generally good (and scary) ideas and creating movies with the skill of a third rate pornographer. The movies are sold based off of special effects and shock value rather than what is truely scary/interesting about a the movie; rather than exploring the concept that "you can buy anything if you have enough money" you get to see a girl get her eye burned out with a blow-torch.
The same basic problem exists in all forms of popular media including videogames; personally, I don't see it as being a problem with the quantity of violence as much as the entire movie/games is focused on the violence rather than on something more meaningful.
