My प्रिय has to be Season 6 because it's Doctor and the Ponds just having adventures and RIVER IS QUEEN. But, my least प्रिय would have to be Season 3 because Martha wasn't a super interesting companion.. I did प्यार those episodes where 10 turns human but..
प्रिय season: Season 3, because Martha "Boss नितंब, गधा कुतिया, मतलबी who doesn't take the Doctor's shit" Jones and the Master were in it, या Season 5. Fetus Roramy and वैंपायर in Venice is what keeps me going.
Least प्रिय season:.. Hmm... Probably season 8, even though I प्यार it, some of it just bores me. I get to see my क्वीन Clara though so it's ok (◡‿◡✿)
