"The Americans feel we're no longer fit for purpose - we need a scalp."The plot's setup is that Harry (played as always by Peter Firth) goes on the run believing that someone inside MI5 helped the CIA's most wanted terrorist Adem Qasim (Elyes Gabel) escape from a gridlocked prisoner handover convoy. Intelligence chiefs blame Harry for putting possible civilian collateral damage ahead of the prisoner's continued detention.
With two people on the loose, the film criss-crosses UK locations and the German capital (with the Isle Of Man ably standing in for the south coast of England) as MI5 search for Harry who they hope will lead them to Qasim. Kit Harrington plays Will Holloway, a decommissioned agent that Harry – and then MI5 – reaches out to; his Game of Thrones sword swapped for a firearm that fits into the back pocket of his jeans.
It's classic Spooks, wrapped up like a feature length end of series episode. Characters you've just grown to like are sacrificed with a pull of the screenwriter's trigger. The fanciful MI5 teeters on the edge due to one botched job, completely overshadowing the hundreds or thousands of other operations and threats they manage. The instability of state organisations is vastly overplayed and nearly stretches the plot beyond a reasonable level of infeasibility.
Spooks has successfully transitioned from television to the big screen. The familiar grey vistas of the London skyline and concrete building are there, though the film budget extends to helicopter shots, trips to Berlin, and CGI explosions.
All in all, if you're a fan of the show, Spooks: The Greater Good is well worth a trip to your local cinema.
