The most obvious thing to note about Heaven Sent is that it's the first time ever the lead actor has had the entire show to themselves (minus a brief appearance from Jenna Coleman and a child actor at the end). It's the sort of thing that can be done every so often, a tweak to the format to keep things interesting. It doesn't hurt to alter the audience's expectations either1.
It worked largely because of Peter Capaldi. Chris
Eccleston could have done this but there was no way the programme could have
been so experimental in its first series. David Tennant could have done this
too, although his Doctor was written more to bounce off of other people and to
enjoy showing off. And even his time on the show may have felt a little early
to try it. Matt Smith could not have handled this, which makes me think that
Moffat's had this story in his head for a while but waited until he had a lead
actor who could do it justice2. I'm finding myself thinking that
more the more I watch Capaldi and see the things he's given to do.
The episode ended up as a fifty-five minute example of
why Peter Capaldi was cast as the Twelfth Doctor. He showed his impressive
range. He showed his instinct for making interesting choices for how to play
things. He showed his expressive body language and facial movements. Whether he
was stepping out of the teleporter at the start (and the end) of the episode
and placing his feet to suggest frailty and innocence or giving a knowing
glance to the camera as he delivered the line "I'm nothing without an
audience" he was pitching things perfectly. He gave a performance that was
so nuanced and focused that he pretty much made it so that he has to be considered the best actor to
have taken the lead role of New Who. Because nobody else has had the chance to
show their ability in this way before.
Steven Moffat deserves credit too. Because he provided
Capaldi with a script that let him be intelligent, funny, scared, angry and a
bunch of other things. He also gave us his best new monster for a while, the originally-unnamed
shuffling presence (later disappointingly named as the Veil) that hounded the
Doctor through an otherwise empty castle. A faceless, unstoppable horror that
can only be stopped with fresh truths is a very clever, very Doctor Who, very
Steven Moffat idea. The same goes for the setting of a castle which can
rearrange itself. That's not a new idea, of course, but it's something that's a
good fit for this show and feels like it should have been seen more. It was the
setting and the constant threat of the Veil that gave the episode a sense of
urgency, something for Capaldi to react against in the absence of a proper
supporting cast.
Moffat's other triumph was explaining how the Doctor
copes with dangerous situations. He stays calm and imagines himself in the
safety of the TARDIS, slowing things down and letting himself concentrate and
think. It gave us a glimpse inside the Doctor's head but in a way that didn't
reveal too much of the character and retained some of his much-needed mystery.
It also made good use of the TARDIS set, an enormous expense that hasn't had
much screen time this series.
Speaking of which, the production team deserve a mention
at this point. They found a great location for the castle, created some good
props to make it seem appropriately unknowable3, and put together an effective costume for the
Veil. Interesting things were done with the lighting as the TARDIS "came
back online" too. Everyone seemed to be working towards making this a
memorable episode and they accomplished that goal.
The episode wasn't without its faults though. At the same
time as he was doing his best writing yet for Capaldi's Doctor Moffat was also
pumping out another looped timeline plot. These and the not dissimilar time paradoxes
are amongst his most overused tropes. He's been using them since Blink and
hasn't been sparing about it. Series six was bookended by this approach for
example. It's reached the point now where it's to be expected. The moment I saw
a gnarled, bloody hand pulling a lever at the beginning of the episode I knew
it would turn out to be Capaldi because that's precisely the sort of thing
Moffat does.
The other failure4 was that it was the Time
Lords behind it all. On one hand, that's okay. The Time Lords have been built
up since the reboot as an unknowable, god-like race whom the Doctor both misses
and never wants to see return. They're an interesting concept to introduce to
New Who5 for these reasons and it feels appropriate for them to
return ten years on from the revival. And the reveal that the castle was inside
the confession dial was a very nice touch, being unexpected and a nod towards
the race's knack for bigger-on-the-inside technology.
On the other hand it was always going to be the Time Lords and Moffat didn't even try to
hide it. A token attempt at not making it obvious would have been nice. Their
return has been inevitable since they were brought back in The Day of the
Doctor and it's an ill-fated decision. The Time Lords have always worked best
when presented as a corrupt society of paranoid schemers desperate to cling to
life and left mostly off-screen. The majority of JNT's term as producer bears
me out on this. The trailer shows that
we're going to see guns and armour. Lots of guns and armour. Using the Time
Lords as Imperial storm trooper surrogates does them no favours but it's not a
part of this episode, so it's not the problem that another time loop plot is.
This isn't the sort of episode that could be done every
series, or even with every Doctor, but as a one off it absolutely works. The
right actor got to do it.
***
1 By "the audience" I mean the
portion of people who watch Doctor Who without gorging themselves on previews
and spoilers first, because they're the ones who (probably) didn't' know this
single-hander was coming, and I imagine it would have worked better without
that foreknowledge.
2 Although I may be giving Moffles too much
credit. Maybe Smith's era was shaped the way it was because he simply couldn't
wait to write all those "clever" time travel plots and explain The
Mystery of River Song™.
3 Yeah it was mostly big clockwork cogs, but what big clockwork cogs!
4 Aside from the script raising questions like
"Why did the Veil touching the Doctor's face burn one side of the face but
not the other, and why did it scorch the Doctor's clothes?"
5 Well, reintroduce,
technically. RTD beat Moffat to it by several years, although it feels like
Moffat intends to have the Time Lords return on a more permanent basis where
Davies was happy to use them as a one-off, the ultimate threat in his
Buffy-inspired Ever Bigger and Badder Big Bads approach to series finales.
