People who have never been to L.A. really have no idea how insanely huge it is. Driving to my apartment from the start of city (before you even get to L.A. county) and having the city just keep going and going and going for two hours and not because of traffic jams is something you have to experience to truly understand.
I don't blame you for that. I would also never go to L.A. as a tourist unless I knew someone to actually show me around the city and know where to take me.
Otherwise you think that it's worth doing things like walking down Hollywood Boulevard and seeing the Chinese Theater and it really isn't unless you actually plan to go watch a movie there. And even then, there's better options.
(That said, the only time I went, I got invited to the Aliens vs. Predator premiere and we ate really potent cannabis brownies beforehand and I was so high I barely remember anything about that movie, so I could be wrong and it could be the best theater in the city. But I vaguely remember it as kind of unimpressive.)
But yeah, unless you are going to a specific place in a touristy part of town, just don't ever go there. And find someone who can tell you where the places that are worth going to are, like the beaches that are not full of idiot tourists and the museums that would actually be worth your time (I miss the Museum of Jurassic Technology so much)...
The MJT looks like it is worth making a huge detour for
Absolutely. It is one of the best things in L.A., or at least was when I lived there.
