Two nits:
1. I saw Thanksgiving in an AMC theater, which means it was full of young, obnoxious, loud teenage boys without parental supervision. They talked and horseplayed for the entirety of the film, so I was on edge throughout.
2. The frequency of cussing in this film, particularly the f-word, is off the chart. It is not central to the storyline, so all it does is distract from it (and painfully so), but that's the bargain one makes when imbibing in Eli Roth concoctions.
Those nits aside (especially nit #1), Thanksgiving could theoretically go on to become a really cool film franchise in the same vein as Halloween.
The film generated just a little less than $13 million at box offices around the world, however, so continuance seems unlikely.
Too bad, because it was creative, spirited, and showed a lot of promise, my second nit aside.
