I think I disagree with every positive thing I see written about this movie. I'm sorry I took a chance on Puffball.
The story follows a pretty Irish girl, Liffey, while she oversees the completion of her dream home in a remote Irish village. It is a very woodsy area, and there are plenty of scenes in thick forests and muddy farmyards. So it is a very "earthy" movie, and that is what probably drew me to it. Very early on, however, the movie also injects a mystical tone, as we see that Liffey has neighbors who practice some sort of voodoo witchcraft.
The tension builds when it is established that Mabs Tucker wants a baby, but is told she is too old to conceive. She turns to her mother, who believes that Liffey's arrival in the area has upset the natural order of things, and that when Liffey becomes pregnant, it is the baby that was "meant" for Mabs which she is carrying. Throughout this exposition, we are shown close-ups of mushrooms as big as a human head with images of a fetus juxtaposed over it. There seems to be some attempt at symbolism, but when the movie was over, I still hadn't figured out what. I was also surprised to see Mabs serving one of these giant puffballs for dinner, carving it like a roast.
One of the problems I had with this movie is that there is enough human drama that I feel like they didn't need the mystical subplot. Liffey gets drunk one night and has relations with Mabs' husband (which was initiated intentionally by Mabs and her mother), and through a series of circumstances, believes she has become pregnant by him. It turns out that when she had gotten pregnant earlier in the movie by her fiancé, she conceived twins, one of which she later miscarried. So the surviving child wasn't a result of the drunken hookup (this is established because the fetus is too far along to have been conceived when that happened).
Now doesn't that sound like enough twists to fill one movie? Well, they tried to pack much more in there, and I didn't think it worked out very well. Mabs' daughter eventually tells Liffey that her family is using magic against her, and it is also revealed to her fiancé she cheated. Everything comes to a climax at the moment Liffey goes into labor and needs to get to the hospital immediately for an emergency c-section. Except that Mabs won't help her out of spite, and her husband is busy having a fistfight with the guy she cheated with. Will she make it? I thought the ending was very anticlimactic, and that is a big part of the reason I rated this so low. It also got a bit tiresome seeing Liffey with blood running down her legs three or four times, gripping her stomach in pain. A scene like that if effective when used once. The director ends up looking a bit overindulgent, and the nearly two-hour running time doesn't help much either.
In closing, I also want to say that a lot of the praise I see written about this movie seems to be from reviewers who end up sounding very pretentious. So if you like to ascribe meaning to vague, symbolic imagery, or you like to focus on attributes like "the architectural quality of film" (???), you may have lots to enjoy with Puffball.
