Doctor Who returned to BBC One on Saturday night with its highly-anticipated first episode of three 60th anniversary specials – and it's safe to say the premiere went down a storm with viewers.
The Doctor finds himself in London after a spaceship crashes in the middle of the city. One of its escapees is The Meep, who is on the run from "monsters" who want to kill it.
The new episode also marks the return of showrunner Russell T Davies, who is back at the helm to celebrate the show's 60th birthday.
Viewers were quick to praise the drama-filled episode on social media, with one person writing: "The new Doctor Who episode was just SO good! Can't wait for the 2 other parts! I haven't smiled, laughed and cried in Doctor Who for such a crazy long time! It feels good! I'm so glad Russel T. Davis is back!" while another added: "Doctor Who special is so amazing and emotional. I'm crying buckets. Thank you!! #DoctorWho60 #DoctorWho."
A third fan remarked: "Absolutely loved #DoctorWhoTheStarBeast #DoctorWho60 this evening on @BBCOne. Fun, thrilling, moving, amazing writing & visual effects, action, and many goosebump moments. Incredible performances from all & total escapism. I need to watch it again."
Viewers also gave a warm welcome back to David and Catherine, with many delighted to see the pair reunited on screen after all these years. One person tweeted: "The first #DoctorWho60 special was brilliant, loved every minute of it and was very impressed with the use of the bigger budget! It's wonderful to have David Tennant and Catherine Tate back together as well," while another penned: "#DoctorWho60 special was fantastic. Absolutely loved having David and Catherine back."
Many fans also praised one particular aspect of the plot, which explores Donna's daughter Rose's [Yasmin Finney] identity as a transgender woman.
One person wrote: "Amazing return from #DavidTennant. He had me at allons-y! His depth was on full display & the dynamic with #CatherineTate, perfect. Overjoyed by the emphasis on trans identities as a plot point and more than just a casting decision," while another added: "OMG the 1st 60th special was amazing! No spoilers but the representation is so wonderful! Disability, gender, pronouns etc! Great work to everyone involved!"
