While Doctor Who is known for its long, timey-wimey arcs, the British show is also home to incredible standalone episodes that have attained fan-favorite status over the years.

Now in the 1930s, he reunites with his daughter River Song, who is working as a private detective called Melody Malone, while Amy and the Doctor try to find a way to bring him back.

While on the job, they encounter the Doctor's old companion, Sarah Jane Smith, who's also doing her own investigation around the school. Now reunited, the Doctor and Sarah seem to fall into old habits, making Rose weary of her own importance to the Timelord.

The success of "School Reunion" led Doctor Who head writer Russell T. Davies to create a spin-off titled The Sarah Jane Adventures. Seeing the Doctor interact with Elisabeth Sladen's Sarah Jane is definitely a treat and gives an insight into his past and his character.

He takes a four-hour shuttle ride to his destination alongside six other passengers, including recently-divorced businesswoman Sky Silvestry. The Doctor is just getting to know his companions when a mysterious being creeps inside their shuttle and possesses Sky, making her repeat everything the others say.

"Midnight" is one of Doctor Who's most suspenseful episodes, made so by the cast's superb acting and the strange alien entity's lack of corporeal form. "Midnight" is a perfect episode for fans of locked-room mysteries and is the first of a few "companion-lite" episodes in which the Doctor goes solo for most of the runtime.

The Weeping Angels make their chilling debut in the fan-favorite "Blink." The episode is written by Steven Moffat and has Carey Mulligan as Sally, who takes on the lead as the Tenth Doctor with a minimal but vital role. Many consider "Blink" to be new Who at its best, with a great dose of good acting, creepiness, and timey-wimey goodness.

After losing Clara, a grieving Twelfth Doctor is teleported against his will into a room inside an old castle. A hooded figure, his captor, keeps following him around and tormenting him, asking him questions that the Doctor doesn't want to answer. As he tries to escape, his mind keeps wandering back to his TARDIS and Clara, who helps him understand what's happening.

"Heaven Sent" isn't technically a standalone, as it's the middle episode of a three-parter, but its structure allows the episode to work by itself. "Heaven Sent" reads like a Shakespearean play, with the Doctor going deep into his own psyche as he deals with Clara's demise and his uncertainty. Peter Capaldi's superlative acting is the driving force behind the entire episode, giving the Doctor a new introspective quality that he previously lacks.
