Bakemonogatari what's this all about?

Just started this anime, only saw episode 1.

I didn't understand the story, and I don't even remember the characters names, and in some point of the episode I got completely lost...

I'm giving a shot at this anime, because I read online that it was very good, and it's supernatural.

I don't know what it's about yet, but when I reach episode 5 or so I'll post something here (I'm hoping that by then I figure it out).
