The problem with the film is its unfulfilled potential.

Rating: 5/10 (24 December 2019)

Others have mentioned the old house might have held some secrets (it didn't). Or that it might present a more structured "Whodunit" that leaves you guessing (it didn't). Or that the main character might offer a bit of verve, cleverness or pizazz, that might have livened up the whole affair (she doesn't, at all).
I also take some issue with the director's choices in scene framing, especially in the beginning. There should have been more close-ups, and better initial intros for each character's little idiosyncrasies so we would could warm up to them. I simply don't care for how it was shot; it's terribly pedestrian. The fast, quick edits of the trailer are totally absent! There's something missing here. Todd Solondz, Tim Burton or the Cohen Brothers really could have drawn these characters out more and given the actors something real to work with.
I thought it would sparkle with a bit more witty, dark humor. It wasn't quite as funny or snappy as I was expecting it to be. Instead, it settles on delivering more of a "message" about this girl, who does good, while the others do bad.
There's also no need for Daniel Craig's poor Southern accent. He should have just done a British accent, it would have been fine and enjoyable, maybe given the film a bit more weight it seems it was shooting for, in the end, with its messaging.
Additional viewings might reveal there's more to it, but I suspect such might reveal there's less.
