Mirk writes "The first episode of Doctor Who's new series 5 has just aired on BBC1 in the UK. This is an important episode for the show because so much has changed: Matt Smith plays the new Doctor, replacing David Tennant, and Karen Gillan portrays a new companion, Amy Pond. Maybe most important, Russell T. Davies is replaced as showrunner by Stephen Moffat, who's known for acclaimed Doctor Who scripts including The Empty Child and Blink. The Reinvigorated Programmer offers an early review of the new Doctor, companion, showrunner, and series."
