Female Doctor
18 October 2014 | by SpoodermanDerpSee all my reviews

Flatline is an episode which truly highlights Clara as a definitive companion or might as well the definitive female version of the Doctor. Not only does it depict Clara as a intriguing and well developed character it doesn't fail to give us a thrilling and satisfying episode.

The episode kicks off as the TARDIS is shrunk for some reason (and may later be explored and explained more in the future) and the Doctor has no choice but to trust Clara as an interesting case develops. The villain in this episode was creative and reminded me of the "Vashta Nerada" back from Tennant's run. They were terrifying, menacing and overall great villain. Clara was remarkable in this episode as effortlessly played by Jenna Coleman. The best Clara episode so far which makes her stand out from all the other companions. She truly was the "Doctor" in this episode and it can be seen that she is the Doctor in the past episodes. This episode makes me feel excited and even hopeful to have a female Doctor after Capaldi. A female Doctor could show that the show can remain intact and well even at a major change. Capaldi's doctor still remained and shined throughout the episode, even if he was just shadowed by Clara throughout the episode he was damn entertaining to watch. The narrative is normal Doctor Who plot, but it was executed well with some twists like Clara being the Doctor.

This episode is a step forward for Doctor Who, as proved by Clara. She might as well be entering the top 5 companions in Doctor Who for me because of this season and especially this episode. If you don't like Clara, watch this episode and you will instantly be hooked with her. And for those who love her already, you'll instantly fall in love with her in this one. With +Clara as the definitive female Doctor, +Menacing villains with riveting abilities, +Capaldi's doctor able to cope even with Clara as the star in the episode. +A well executed episode. Season 8 just keeps getting better and better.

Verdict: 8.6/10
