I do love genre movies, and have seen lots of them in theatres, rented lots more and even waited for the public library to get some because they don't deserve my rental dollars (Transformers). But looking over my stuff, I've be surprised if I have more than ten genre flicks from the last 5 years.
Taking into account that I'm only talking about films, not Television series, here's what I've got.
In Fantasy since 2004, I own Pan's Labyrinth, Mirrormask, Lady in the Water, and Stardust, all of which I've watched on DVD at least twice, most of which I've checked out the special features on. When I think of spending money on Fantasy films, I just find that a lot of it ends up going to stuff that would be perfect Christmas or Birthday gifts for my daughters.
In SF since 2004, I own Children of Men and Sunshine. I know that you can consider most Super Hero flicks to be SF, but as I buy most of them for my kids, they aren't really my collection. To be fair, since my BFF Mike is a huge SF and Super Hero fan, I can borrow these titles from him so there isn't as much of a need for me to purchase these.
In Horror since 2004, I've got Shawn of the Dead, Planet Terror and Slither. I am a pretty big horror fan, but even taking into account the 2009 horror films I'd like to own (Drag Me To Hell and Zombieland), I'm just not finding a big need to re-watch a lot of newer horror movies.
When I think about a movie that I might like to own, I have three filters that make sure I don't end up broke (pictured right).
1) Do I have somethings I'd rather do with this $20 bill?
2) As much as I liked it in theatres, will I ever re-watch this film?
3) Would I be embarrased if someone saw this on my DVD shelf?
I still by a lot of DVDs, but these days more of them tend to be hard-to-find classics and hidden gems of genre films. I hope that means I'm getting more discerning in my selections, rather than just being picky.
