Neil Gaiman (neilgaiman.com) talks about this issue too in his blog and gives some advice to readers.
His blog entry about the Harry Potter Lexicon court case, correct? I think that the company and author who are publishing the book have a very hard case to prove. Copyright does protect an author from others making derivative works. I am not certain there has ever been a case that covered an encyclopedia about "facts" from a work of fiction, but hopefully you understand why I say that the Lexicon could be judged a derivative work. I am also interested to read that court case once the court’s findings are published.
I have prepared a short list of movies that I financially supported by buying or renting after reading reviews on your site. Anyone who gives you crap about your use of the fine movies you feature is either a moron or malicious.
I'll agree here. There are a lot of movies I've purchased and/or rented after reading reviews from this site. Based on the content described and the images provided, I've been able to make informed judgment about which movies I want to track down and watch (and some of them took a lot of looking to find). Personally, I feel this site provides a great service to those of us who enjoy movies like these. It provides great exposure for many films some of us might never hear about otherwise.
I have not really had problems with copyright holders trying to push me around by sending DMCA or takedown notices over the years. There have been a couple, but they have never gone past one or two cease and desist emails. Once I respond back, we usually either work the situation out, or else the person completely dropped it and never emailed me again.
The good thing here is that my goal is to operate within fair use. I am not trying to infringe on the copyrights of the movie's owners, but want to review their work, discuss its aspects, and even what it made me think about. If the review adds something to culture and provides a service to readers, then that is exactly why we have fair use - so that can happen.
