And for this Eli Roth thing we are truly blessed

It's got everything you expect from Eli Roth: gore, comedy, Massholes, good direction, good cinematography. It's slick and well done as a turkey...you'll see :)

So it opens on Jessica. She has agreed to meet her friends and go to the movies after dinner with her family There's some set up of the movie's relationship dynamics and lays groundwork for later
In the car one of her friends asks if they can go to the local mega store on Black Friday as their phone needs replacing and plan to skip the queues using the fact that Jessica's father owns the store to their advantage.
One of the  people in the crowd got in a fight with Jessica's friend and her boyfriend recently and so they taunt him a little, enraged he takes a megaphone from an employee and declares the store open causing a stampede that kills many people. One of Jessica's friends films and uploads the event online and we get a One Year Later timeskip.
It's somewhat similar to My Bloody Valentine with Jessica's boyfriend being injured, disappearing for a bit and returning mysteriously.

Since the event, her friend has taken down the video he made and never wants to be associated with it ever again but someone keeps uploading it and eventually tags Jessica and her friends as guests at a Thanksgiving table. Bit by bit the table is filled with the bodies of people who were at the massacre.

It's a wonderful example of a slasher movie, full of loving homage, dark humour and it's so much fun.

Thanks Eli Roth for this Thanksgiving feast.

The killer is not hard to spot if you pay any attention at all but even if you guess right away, watching them execute both their plan and their killings is so entertaining it doesn't matter.
