Class: 5 More Doctor Who Spin-Offs We Need To See

The Sarah Jane Adventures ended too soon for tragic reasons. It was perhaps the best-written show on children's TV for a long time, and it provided exciting new storytelling for a demographic that really deserves it. It was relatable for young audiences because it operated at a domestic earth-set level, focused on an unconventional family, and the fantastic happenings in an episode offered escapism once a week.

So many threads were left hanging in the middle of production of the fifth season, with new characters only just introduced - audiences have unfinished business with a show that didn't necessarily have to finish. The Sarah Jane adventures needed Sarah Jane, but a show featuring everyone else but her only needs her incredible legacy to continue.

A respectful return with the original cast, set in the same location with Jo Grant or other old companions like Ace - whose returns were planned - would offer great family drama and satisfy fans of the classic series of Doctor Who. As a continuation, not a sequel, of the world created in SJA, it doesn't have to exclude memorable characters like The Shopkeeper and The Trickster.

With Class now covering young adults, if the BBC produces a more child-oriented spin-off, then virtually every demographic is offered something within the Doctor Who universe.
