I just had a partial knee replacement last week and now that I will be out of work for a while I think it is time for a Doctor Who marathon.  I have seen some of the old episodes but not many.  Any suggestions of where to start?

This is what happens when the TARDIS takes the Doctor to the Star Wars Universe.  LOL  I am trying to design one for the current Doctor now, but it is much, much more complicated than this one was.  Open to suggestions.
