Considering what a monumental development Sarah Jane’s wedding is for the show it is a shame that this story suffers from a boiler-plate plot. While it’s not bad - it’s pretty damn predictable and the Trickster's motivation to stop Sarah Jane meddling with history seems pretty weak. I appreciate however seeing Sarah Jane being given a more romantic side to her, showing her as a three dimensional character. It is more than saved by the excellent cast which as a one off includes David Tennent in one of his very last regular appearances as the 10th Doctor. It is a stellar performance which was filmed AFTER he had finished filming on Doctor Who - what dedication.
