Review of Heaven Sent
Warning: This review contains episode-specific spoilers and wild speculation about future episodes.
Heaven Sent is what, back in the day, my Star Trek: The Next Generation-watching friends and I would’ve called a Mind F*** Episode. You watch the whole thing thinking you understand the basic problem the crew (or, in this case, the Doctor) is facing until the very end, when one new piece of information changes how you look at everything else.
It’s a tricky stunt to pull off, especially given the nearly completely solo acting required of Capaldi. In the entire piece, there were only three other characters; only one of those ever spoke, and that was a single line to which the Doctor made no verbal response. In the hands of a lesser actor, it could have been disastrous.
Instead, it was suspenseful and engaging. That first time through, as is often the case with a Moffat script, you can see there are big hints being dropped, but you can’t necessarily put together the puzzle (at least I couldn’t—YMMV). Once you know the scoop, though, every little detail takes on new meaning, both just when thinking back on it and upon repeated viewing.
However, I found I enjoyed this episode more than almost any Moffat-penned script since he took over as showrunner. Usually Moffat’s episodes start to unravel upon closer inspection. That’s not the case for me this time. Only one thing bothers me, and it’s something I can fan-theory away if I try. In my book, that makes this episode a huge win in the Moffat-as-writer category.
