Although this episode has tons of action with Jon Snow and his ranging party battling an approaching horde of wights, many fans couldn't abide by far-fetched nature of the episode's logistical elements. This includes but is not limited to the unbelievable foot race time on Gendry's trek back to the wall to seek help, the deus ex machina rescue by Jon's uncle Benjen, and the fact that another one of Jon's dumb strategic moves gets Daenerys's dragon killed.
