Stranger Things Content Question

I’ve watched the first two episodes (and pre-title sequence of ep 3) of Stranger Things and I really want to watch more, but I’m very squeamish about TV/movie gore.  My delicate, couch-fainting constitution can mostly handle the jump scares and general spook, but can anyone give me **spoiler-free** heads-up if there’s any graphic violence/torture in the remaining episodes?  I just want to be prepared.

Thanks!!
