The overall violence is very occasional. It is more about the consequences of a science experiment more than the grotesque sequences.

R violence type: blood and gore.

During a sequence in the first half of the film where the main protagonists have just had sex, a computer chip becomes stuck on the man's back, making him jump in pain. The woman gently peels it off him and we see three small, bloody cuts on his skin. This is shown in a close up and lasts for a brief second.

The ending is very depressing and heartbreaking.

There are almost no jumpscares in the film, and it instead has a slow, gradual build of tension making for a consistent sense of fear and dread throughout the entire movie.

Seth's decaying into a human-fly hybrid is utterly disgusting and extremely disturbing. The body horror practical effects used in the film still hold up to this day. These scenes are very hard to watch, even for those tolerant of gore.
