The "Doctor Who" spin-off has been called the British "Buffy" for its heart and charm, which prevails in each episode. "Class" continues to get stronger (and delightfully stranger) as the characters continue to bond over alien threats and personal struggles. Everything that makes "Doctor Who" wonderfully quirky and fun is found in "Class." The BBC drama knows when to bring the humor, but also isn't afraid to pull no punches with emotion. The series stars Fady Elsayed (Ram), Greg Austin (Charlie), Sophie Hopkins (April), Vivian Oparah (Tanya), Katherine Kelly (Miss Quill), and Jordan Renzo (Matteusz).

BBC America releases descriptions for next two episodes

Dealing with the aftermath of April's takeover of the Shadow Kin, Charlie's near decision to use the cabinet as a weapon, and Miss Quill's alliance with the new headteacher will continue through the remaining episodes of the season. The May 20 episode of "Class," entitled "Detained," is described by BBC America: "The whole gang is thrown in detention by Miss Quill. Locked in her classroom, they are terrified when an explosion propels them out of space and time, and floating in blackness with no way to escape." By the looks of the promo, the group will be dealing with conflict amongst themselves when they're forced to express the truth.

Episode 7 of "Class" will continue on from episode 6, and is entitled "The Metaphysical Engine, or what Quill did." The Quill-centric episode is described as follows: "With the gang trapped in detention and out of the way, Miss Quill accepts Dorothea's astonishing offer: to help remove the Arn from her head, and to reclaim her freedom." The episode will air on May 27 on BBC America.

Why people should watch 'Class'

Television needs more shows that aren't afraid to dig into characters, conflicts, and struggles, while being relatable enough that you can learn from them. In the same vein that "Strange Days of Blake Holsey High" used science as a metaphor, and "Buffy" used demons, "Class" uses aliens from outer space.

It's marketed as a teen drama, but it branches out way beyond that. There is an alien threat of the week, but the series tackles real life, allowing the characters to grow and learn. One episode deals with Tanya's grief about her father's passing and questions death itself, and in another, April's estranged relationship with her dad is tragically revealed.

The dialogue is witty in the same style that "Doctor Who" does so well, but the themes are dark. "Class" doesn't shy away from grief, loss, and questioning life's purpose, but the series also exceeds in making the characters stronger through each obstacle. It's not about the killing petals, instead, the threat of the week leads to Charlie's (Greg Austin) internal conflict about the difference between justice and murder, while April's (Sophie Hopkins) quest to get back her heart allowed her to go to the darker side of her nature and the person she is.

"Class" makes every character layered with flaws, strengths, and struggles. Even Miss Quill (Katherine Kelly) who was a "freedom fighter" before the loss of her and Charlie's planet has worn her heart on her sleeve when expressing the grief and rage for the loss of her people. They're not perfect, and that's what makes the show excel.
