Ram 3500 4x4 getting stuck in snow that isn't even deep. Not a chance.
Alaskans do not leave doors open in the middle of winter. And, most have two doors, with a little porch between, to help keep out the cold.
When the camera gets a closeup of two of the snowmen being built you can tell they are Styrofoam balls instead of snow.
At the beginning of Act II, Matt's Ram 3500 4x4 get "stuck" in 1 in snow (which was pointed already)! Even more absurd scene is behind Jessica and Matt's backs - beautiful green deciduous trees and plants. But there is more. In Act III, Jessica run out of party venue into backyard to talk on the her cell phone. She was only in her red dress. Matt comes after her walking and wide camera shot show a lot of beautiful big green deciduous trees and plants. He said to her "You got a be freezing" except she didn't as she didn't tremble nor there was air condensation from their mouths. And that was all in the mid/late of December in Alaska! Obviously was shot in spring and/or summer.
Around half of movie, Jessica and her sister Kara have FaceTime video call. Jessica was using iPad, and Kara Windows laptop. However, video call was pre-recorded as both sisters portraits were static on selfie camera on their respective display which is impossible as both sister clearly see each other as live stream and not as static picture.
