TIFU by introducing my family to death note

So, this happened last night, but the fallout came today. Last night, my family (my two parents and sister (22f)) were browsing TV for something to watch. I’ve been watching the show death note, recently, and have gotten really into it, despite not being too into anime. I suggested we watch the first episode, thinking my parents might enjoy the plot. I skipped the theme song, knowing my dad would find it irritating. I explained a couple plot points at my dad’s request. Anyway, we watched it, my parents mostly enjoyed it, and that was that. Today, my sister started saying that our parents shouldn’t watch it, because she didn’t like skipping the theme songs, because it wasn’t watching it properly, and that I ruined the entire episode by talking during it. I told her that mom and dad liked it though. She went on to aggressively tell me that she’d had it on her watchlist for way longer than I’d been watching it for, and to stop treating it like it was my thing. This devolved into her yelling and swearing at my mom and I, saying she was going to watch the whole series in the next two days, so that my parents wouldn’t be ahead of her in an anime. It got so loud my dad, who works from home, came storming out of his office to see what the commotion was. She kept giving me dirty looks as she left for school.

TL;DR Watched an episode of death note with my parents, and caused total chaos within my family.
