Doctor Who: The Complete Fourth Season

One of the great things about the modern-day Doctor Who is how, each season, the episodes build off each other to help create truly epic and rewarding finales. This has never been more true than in the 4th season of this fantastic series.

This year, the Doctor takes on his third human companion, Donna Noble, who actually appeared in the season 3 premiere. While it's a rocky start for the pair--Donna lacks Rose Tyler's sense of wonder or Martha Jones's intelligent wit--she proves to fill the role admirably. Among their adventures: A meeting with Agatha Christie, a history-bending visit to ancient Pompeii, and the threat of foes both old and new.

But (SPOILERS AHEAD) the real treat of season four is the welcome (albiet somewhat brief) return of Billie Piper as Rose Tyler. And not just Rose, but ALL of the Doctor's recent companions, plus Torchwood - The Complete First Season's Capt. Jack and classic WHO companion Sarah Jane Smith (The Sarah Jane Adventures - The Complete First Season) are along for the 3-part season finale. I don't think it's a stretch to call the extended finale "Journey's End" the crowning achievement of the Doctor Who revival series. By A. Gammill
