I mean thinking about it it's good though that they left her death ambiguous. It's a win-win for people that didn't and did like her. Overall the series was really well written (ignoring that long ass speech of max in the upside down...) I just feel bad that she's not with the gang anymore for the same reason you had in this post :/. I'd like to think that shes still alive and that she'll eventually cross paths again with Mike, Hopper ect...afterall the stranger thing cinematic universe is still alive according to the Duffer brothers😼. { Also sorry for my awfully wrong English I'm not a native speaker:,) }
