Hmmm... "Back of the box" descriptions rarely do it for me these days. Nowadays, I take chances on indie films with "no name" actors based on USER REVIEWS via Netflix, Imdb or fellow filmmakers found here. If there's someone whose opinion and sensibilities I trust and they give a particular movie "thumbs up" or "gotta see" and the genre and/or content is of interest to me, I will give it a look. Also, if a film is critically praised, I am more inclined to learn more about it.
Although user reviews are not a failsafe method (Netherbeast Incorporated!!

), but for the most part I will scan comments to get a cursory idea of what is to be expected.
I tend to seek out dark psychological suspense thrillers and if there's an element of sci-fi fantasy and horror, all the better, but that's not all that we/I watch. The other night we streamed
Oliver! the Musical (196

and I was absolutely stunned by the set design, choreography, blocking (boggles the mind!), extras, and costumes. All real, all amazing. What's crazy is that nowadays, instead of casting 100 extras for background work, they have 100 CG artists creating the background extras. Wild.
But as far as BUYING dvds is concerned, I think the last one I bought was Scrooged

3 years ago at a Rite-Aid for $9.99. Just don't feel the need to own many.
