This is maybe a bit rambly, but I'm considering adding it to the OP.
So occasionally I am reminded at just how weird some people who know me think my fascination with schlock cinema is, especially with the more horribly offensive stuff like Blood Sucking Freaks. I'm very politically left with a lot to say about various -isms, especially within the cultures that I'm a part of (geek, atheist/skeptic and metal communities especially) and generally I find a lot of the things that are common tropes within schlock to be absolutely lazy and rarely used to good effect outside of the genre. I don't think Political Correctness is "out of control" because fuck you, at worst it's a societal contract to not be a fucking asshole and consider how others might take your bullshit. I think that if you believe art, cinema, literature and such can improve a culture, you must also accept that it can also negatively impact it. I do not think Joss Whedon is a feminist, whatever he ʎɐW believe, nor do I think he does a particularly good job at subverting the -isms he openly claims (and fans claim) to avoid.
I also happen to love this realm of cinema that regularly makes light of rape, sexual assault, racism, classism and a lot of other really touchy topics.
I'm absolutely not going to defend any of these films. I also refuse to be the unfortunately common kind of fan that is actually excited about the fact that the Rape Tree is coming back in the Evil Dead reboot. I love this genre, but I'd prefer to leave a lot of it's tropes in the past, where they belong. Newer schlock films that I enjoy tend to be of a very different style than those from 15+ years ago and it's rare to find ones that keep the same level of love for the artform, but also an understanding of how the world has changed. I want schlock to grow up in certain areas, and the fans make it incredibly hard to do so.
As it is though, I love horror and schlock a lot. Part of what I love about them, is they almost always include a fairly large amount of social commentary about the culture that is commonly lacking in other genres of film of the time. The schlockier it is the more hamhanded it is, but it's heart is usually in the right place. Let's take the 80's for example. How many horror films can you recall that had a theme concerning neglectful parents and the general lack of taking children seriously and the danger that puts them in? The dangers they are put in force them into situations where they must grow in ways they are not prepared for, not because they are stupid or horrible, but because their parents failed to be there when they needed them most. The most famous of them is probably Nightmare on Elm Street, but there were a hell of a lot of them. Of course then there is stuff like Friday the 13th, where the social commentary is stupid teenagers who commit sin die horrible deaths. Those are also great fun. But either way, the point is it's almost as much fun for me to pick apart and analyze these films as it is to just enjoy the stupidity and offensiveness that is so commonly present. This gets doubly interesting when I go into foreign horror films, but that's beside this point.
tl;dr I like schlock which consist of a lot of problematic themes. I know it's problematic and I'm not going to defend it in any way. Give me some feedback on this.
