Netflix seems to use some kind of voodoo for their suggestions. I have expanded my interests because of their recommendations. I also get ideas from podcasters who love the same things I do.
Conventions were always a good place for me to find something new. I got my first Jet Li and Godzilla movies there. This was back when dvds were just coming out and those type of films were not around commercially yet.
I found a lot of favs at Cons too, not just from the dealers but from the fans. Sitting around gabbing about movies and books has to be the best part of a convention. I always discover something new.
