You might as well go see the movie. It's really good. You get to see Samuel L Jackson eat eyeballs. x3 Plus it's a Tim Burton flick, and who doesn't love a tim burton flick? Especially given the Halloween season coming up...
But anyway, I myself generally don't roleplay things unless I already know something about it. And if I don't know anything about it but it sounds interesting, I do the research myself. I don't just demand the host to do all the work for me. Because they probably have more important things to do, like coming up with plot ideas to bounce off people who are interested, or ideas for the setting, the time period, etc. Because if people are interested, then I'm going to have to do a lot of work putting this together, and I won't have time to go and spell every detail out for people who haven't seen/read it, who may not even be interested in the first place.
I'm already giving you a link to the wiki to find out for yourself about everything. Why should I be so invested in teaching you about this book world and putting together this whole darn roleplay when you aren't invested enough to learn for yourself? It takes less than an hour tops to go through the information, maybe more if your computer is a fossil.
Not to mention the fact that I have a lot of responsibilities as an adult in college, and my time is limited.
