• The Room 101 (i.e., torture) scene infers more than it shows, but what it does show is still pretty graphic, particularly in terms of (fake) blood. Winston "bleeds" quite a bit throughout the scene, including spouting blood out of his mouth after his teeth are pulled. And you can't escape the blood, even if you're sitting far away. This is because, in the spirit of Big Brother, much of the play is live-filmed in close-ups and projected on the screen over the main set. So, as blood drools out of Winston's mouth for the 20 minutes or so that the scene lasts (it does really feel that long), you won't be able to escape a blown-up bloodied face. Moreover, Room 101 is completely white, so the contrast of dark red blood with the white floor is quite stark.

(Thanks for the fix, LxGstv!) yes, towards the beginning of the play someone is shown to be shot in the back of the head on film, and it is not subtle. It takes place during the Two Minutes of Hate segment, in which the loud spewing of hate language from people lined up downstage may also be bothersome to people.
• The kissing scene implies rough sex, but nothing is really shown. Compared to other parts of the play, this scene is downright mild.
