It's a very impersonal city. People don't seem to care very much for each other, and it's full of homeless/mentally troubled people.
Parking is hell. Traffic is hell. The city never sleeps, but that could be both good and bad.
Overall, I would say it's a decent experience to have. Wouldn't live there if you pay me though.
As for the safety issue, it depends on which part of the city you live in. Apartments closer to the Santa Monica area cost drastically more, but the neighborhoods outward raise more security concern. Overall, I don't think it's as bad as people make it sound.
