I've had a hankering for some stuff that takes a deeper look at the films lately, so for the moment I'll drop this link in; not sure what I think about it at the moment (frankly, I'm heading to sleep), but it's something I'm going to start looking into. This thread can be a place to put such stuff, for a start.
