This will function as my review of both "Day Four" and Torchwood: Children of Earth so far. It's hard to believe that Children of Earth is a season of the same tv show that brought us alien sex gas. The immature throwing around of sex and gore just because the writers felt like it is gone and replaced by a mature fabulous combination of science-fiction and drama that feels very real and grounded in human behavior. The scene where the government officials are sitting around a table, surrendering to the 456, deciding what children to sacrifice, and deciding to sacrifice disabled and disenfranchised children they see as useless was chilling, but felt unfortunately accurate to how I think real-life government officials would handle this situation. All of the tension that's been building in the first three episodes results in catastrophe in "Day Four", and I can't wait to watch "Day Five". Although John Barrowman was able to pull off the charisma and one-liners required for the role of Jack Harkness in his limited appearances in Doctor Who, his dramatic acting in Torchwood is lacking and clearly weaker when compared to the rest of the cast (especially Peter Capaldi as the mundanely evil middle man John Frobisher).
