>Are you the "cinema is shite" guy?
No. I like movies and my preferences aren't nearly as specific as his and I don't care for crime films.
>these might not be for you
I've watched hundreds of them and "learned to hate" them. I watch lots of different types of movies and for awhile I watched these. Most genre films in general, I dislike now (I used to love horror and westerns in particular).
>You shouldn't force yourself to watch something you don't like and become depressed because of them
I was never forcing myself to watch anything, I wanted to watch them at the time. The reason I eventually found them to be depressing was that such a large portion of them are so poorly made that it's nearly unbelievable, not to mention the laziness and even arrogance that sometimes goes into making some of this crap.
>Care to elaborate?
I wouldn't want to spend time with most people who are into b-movies. From CG, to irl conventions: there are a ton of reference points for you to gather what kind of people generally are into low-budget schlock. I have some personal biases with this as well, having known some people who enjoyed these.
It's all my opinion. I think there's value in watching genre movies, it's just not for me these days.
