Happiest Season felt surprisingly new as a family, love tragedy christmas movie and I really like it. It isn’t an older movie but since it came out, it is a must watch every christmas season.
Before this, it definitely was The Long Kiss Goodnight (and funny thing, the german title translates to “deadly christmas”)
If you’re playing on pc, just look up the mod and try the additional mod “grandpas map” as well! After around 1,500h in SV it feels like a new game with those two mods installed. Cannot recommend it enough!
