I'm with you on most of this but her Holocure streams are fun because those often lead to tangents, they're just usually more vtuber related tangents plus the game in general is pretty fun to watch. You're right about jong getting old though mainly because she played it way too many times in a row plus the way the game works makes it not fit for tangents mainly because of the timer in the game. As for the react streams I agree they're fun the issue is lately the only things she reacts to are those cop videos and it gets a little stale hearing the same exact takes from pretty much identical tangents every time she does one of those streams. I don't mind when she does more of a variety of react content, like the zillow streams or that one she did about weather events the other week.I don't think I can disagree more.
Often times the funnest/funniest part of her stream is watching people's reaction as she completely fails to grasp game concepts or better yet begins to shit on the game as a result (think Amnesia: The Bunker stream). She isn't the best at paying close attention to the story but she pays enough attention to give funny asides and reactions to big happenings in the game. If you want to sit there and really immerse yourself in the story you can just play the game yourself. On the other hand having her play the same two games over and over (jong/holocure) gets stale as there is nothing new to serve as a ballast to guide her tangents. Also why, I know you autists will disagree, her react content is unironically some of her best content. Both for the seething that occurs when she says something incredibly retarded and genuinely entertaining tangents/jokes.
