When two bickering sisters inherit their grandmother?s precious doll collection, they get more than they bargain for with a house horde of dolls, and a demonic entity threatening their life.

There are a few descriptions that often pop up in loglines, one of these is; “…get more than they bargained for…”

In case you’re wondering, another example would be; “…his/her world falls apart…”

The point is that these are a perfectly generic description, and by nature add very little to a logline. Since word real estate is at a premium in loglines, you’d be better of using descriptions that contribute to a clearer understanding of the plot.

Also, it sounds as if the inciting event is the demon appearing, not the inheritance. To that matter, their goal would be vanquishing the demon, which needs to me specified in the logline. Just saying that the demon threatens their lives is an implication that they’ll have to defeat the demon, but it’s not a clear definition of a goal.
