I ran into this Reddit question while trying to research something else. They mentioned this:
I’ve searched a lot for the one big thing I remember but I can’t find anything on it and that is, "kill con". It was something about a big event but deaths keep happening making the title or something kill con. I also remember and I’m not sure about this but I remember there may have been some ghost girl.
They wound up accepting an answer, but another film came to mind that my wife and I watched, I'm pretty sure on Netflix, definitely within the last decade, but probably about 3-5 years ago, prior to our toddler being born. The premise of the film is that a convention for influencers/streamers is being held in a hotel that, unbeknownst to them, is haunted. One of the symbols of the haunting is mascot in a bunny costume. My brain wants to say the rabbit is pink, but I might be channeling Robbie the Rabbit from Silent Hill. As per the Reddit post, I do remember the balloon being a recurring motif, although I don't recall if it was involved in a kill. I think there was a recurring visual motif that the hotel had a mold problem, symbolism of deep-seated rot in society being painted over without fixing the problem and so on. Other than that, my brain has several isolated scenes:
- At the beginning, there's a teletype display, like with an old-fashioned BBS. It might have been paired up with an early murder, which was the start of the haunting?
- Earlyish in the film, there's a series of scenes showing the various influencers descending a double staircase, probably in the lobby of the hotel, with them obviously posing for cameras and filming footage for their channel.
- At some point, it's either shown or highly implied that a cleaning lady (Hispanic?) is killed by the evil.
- I think there was a possession motif where whatever was haunting the motel took over one or more of the main characters, pushing them to violent impulses.
- The end of the film implied that the evil had survived, and might have made it onto the internet.
