Continuity mistake: When Eddie comes down the stairs to ask his father again about wanting new shoes, his father says no. Eddie goes back up the stairs. Next scene, Carl walks to the kitchen, and Eddie is sitting at the counter.
Carl, Eddie, and Steve are out ice fishing. At one point Carl falls through the "ice" and you can clearly see that the "ice" is made of some sort of styrofoam. It looks like the stuff used for packaging. The snow looks just as fake.
