If you remember seeing "Grindhouse", the two film collaboration between Robert Rodriguez and Quentin Tarantino, you will probably also remember that there were trailers between the two films. The fake trailers included two that were subsequently turned into actual films; "Hobo with a Shotgun" and "Machete". We now have a third film based on those fake trailers, "Thanksgiving" is also directed by Eli Roth, who made the fake trailer for a film titled "Thanksgiving" for the 2007 Grindhouse project. Not to disparage the other films, but "Thanksgiving" turns out to be the best of the bunch, at least until "Don't" or "Werewolf Women of the S.S." get made.
After the success of "Halloween" back in 1978, there were dozens of films that took holiday themes to the slasher market. "Friday the 13th", "April Fool's Day", "My Bloody Valentine", and many more. Roth's trailer for "Thanksgiving" is a parody and salute to those types of films. The full film does a great job of following that inspiration by repeating many of the tropes from those films. There is a foundational event that prompts a revenge scheme, we get a masked killer, the deaths are often played out as holiday related events, and there is macabre humor in just about all of it.
This film is very satisfying to those who enjoy a dark humored look at American Traditions and horror films. The opening section includes a scene that reminds us of real world horrors associate with Black Friday sales at department stores. Unruly crowds are pretty darn scary without throwing in the gore, but why skip the gore when you are doing a parody like this, Eli Roth doesn't. He lays it on thick with his frequent use of skin being removed from the body by accidental means. Shopping carts and restaurant freezers are not benign objects in this movie. There are plenty of decapitations, stabbings, strangling's and assorted other mayhem to keep all of the gore-hounds engaged, but it is all delivered with a large tongue inserted into a cheek. When a severed body is displayed next to a 50% off sign, you know that this is not meant to be taken seriously.
With one major plot exception, the film plays out the crimes with a pretty straightforward fidelity to law enforcement investigation. There has to however, be a point at which logic gets defied, and the results show up to start the third act. The creation of a mythical character, John Carver, as the avatar of the killer almost works. Like the Baby masks in "Happy Death Day", this allows for suspicions to be cast on a variety of supporting characters and it adds the requisite mystery to the plot. There are a few moments that brush up against the torture porn that Roth has been known for, but I think it mostly stays this side of being prurient.
There are not a lot of holiday films that feature Thanksgiving as their central premise. It's nice to have one more to add to the list, and especially one as self aware and entertaining as this one is. So fill your plate, over indulge and forget leaving room for dessert, the main course will fill you up and as the tagline says, "There will be no Leftovers".
