This is long overdue. This reboot of Doctor Who is phenominal. The latest, Season 6, is a great story arc that lays out a complex, interwoven set of stories and timelines and makes it all work. Persaonally I think you have to first see Season 5 which introduces River Song to appreciate some of the setup nuggets for Season 6. Better yet, watch from Season 1 onward!
Who is your favorite Doctor and who is your favorite Companion?
I can’t pick a favorite Doctor, they are all too good, each in their own way. But definitely, Amy Pond is my favorite companion.
