The easiest way to love LA is simple. Move here, sublet til you find a job, then move into an apartment < 10 minutes from your job. (Or, if that's not doable, try to move opposite the flow of traffic.)
Moving here, picking a place, and then finding out that you have a 90 minute commute is just a recipe for hatred.
As far as the people -- Yes. There are a lot of self-serving actors, actresses, directors, etc. But there are 9.9 million people in this town, which means that even if the people you are inclined to like are a minority, there are hundreds of thousands of them. And the neat thing is, when they find you (and you them), you'll appreciate each other even more.
