David Tenant (swoon....be still my heart!) contines his run as the Doctor in Season 3 of my most favorite show of all time! Freema Agyeman is his new companion, Martha Jones (she is also a doctor, although an Earth type of doctor). For those who grew to know and love the character of Rose Tyler (played by the wonderful Bilie Piper) as the Doctor's companion it would seem she would be hard to replace. The character of Martha Jones is different than Rose, but equally as well. Freema Agyeman is a wonderful actress and does a great job portraying Martha. More aliens and time travel abound! Also, another favorite actor of mine, John Simms (Sam Tyler on Life on Mars, another brilliant must see show) plays a villian in a few episodes. Check this out and see why it is my new favorite show of all time and the best thing on tv.!!
