Every season of Classic Doctor Who contains a number of “serials” which are made up of multiple episodes. Below is every Doctor Who serial categorized and ranked. I got my list of episodes from the fantastic Wikipedia entry, “List of Doctor Who serials.” I also consulted Nerdist’s “Doctor Who for Newbies” series ( First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth, Tenth, Eleventh ), Geeks of Doom’s “10 Classic ‘Doctor Who’ Adventures Worth Checking Out” article, and Doctor Who Magazine's “Big 200” Reader Poll to make sure I didn’t under represent any episodes. Leave any suggestions for changes in the comments below. If you want to start on a later episode, Ritch and Space has a video that covers good starting points and watching habits.

Another great option for getting started is The Doctors Revisited, a BBC series profiling each Doctor and then showed one of their classic stories. It's a great combination of backstory, commentary, and curated stories:
