If The Doctor offered you a spot traveling with him on his spaceship/time machine called The TARDIS, would you go? Would you still go if you knew what happened to all his previous companions?

In the second of my three-part series on Doctor Who, I look at whether The Doctor's companions are better off in the end -- and why. (Part 2 of a 3-part mini-series)
