No pun intended - and while I am referring to something in the movie (or is it someone?), you may take this as point of reference when it comes to the movie as a whole ... as in this being a B-horror movie and having the usual things you may expect or even fear in it (another pun? Very likely if you know me).
The effects are good for the low budget this has - but you may have issues. We may have seen similar movies and yet this can be exciting and suspensful. If you can suspend your disbelief that is of course. As the poster of course also suggest, there will be blood (no pun intended) and it will go places that some sensible souls may have issues with too ... be aware of all those things ... and if that is something you want to see or not.
