It might be a tad long and sort of underwhelming, but "The Reign of Terror" isn't really that bad of an episode of Doctor Who.

Barbara is mistaken for a goddess, and, much to the Doctor's chagrin, attempts to use her newfound command to alter history ("The Aztecs"). After that, the crew of the TARDIS is met with suspicion by a powerfully telepathic, yet fearful alien race ("The Sensorites").

In the two weeks since the last episode of Bigger on the Inside aired, there have been some major happenings in the world of Doctor Who. Not only has the Christmas special "The Next Doctor" aired in the UK, but the BBC has revealed the identity of the actor who'll play the 11th Doctor starting in 2010! Beyond that, the guys review the six-part serial "The Keys of Marinus," and Mike has a theory about Professor River Song.

After reading several e-mails about Rose, Dan and Mike focus on two Doctor Who stories. First up is "The Edge of Destruction," which takes place entirely inside the TARDIS. Then they lament the tragic loss of the seven-part "Marco Polo," the first serial to suffer from the BBC's junking policy. Also, Mike turns embarrassingly red at one point.

While discussing the title characters of the second Doctor Who story, "The Daleks," Dan puts their cultural impact on British society into perspective, and Mike admits there's a line so geeky even he won't cross it.

Exactly 45 years ago today Doctor Who debuted on the BBC, and it quickly became a cultural phenomenon. Now, all these decades later, Earth-2.net launches Bigger on the Inside -- a deep, analytical look at the program and its impact on the world. Starting off, the duo explores "An Unearthly Child," the four-part serial that introduced the world to the Doctor.
