Speaking of things that the Brits do better than anyone else, crime dramas are at the very top of that list, and Collateral is no exception. The four-part drama aired on BBC earlier this year (and is now on Netflix in the US), and deals with the murder of a pizza delivery guy. DI Kip Glaspie (Carey Mulligan) leads the investigation, and her not-so-by-the-book methods help her get to the bottom of the crime, which is so much more complex than it initially appears.
Written by playwright David Hare, Collateral is hard-hitting drama, but it's not without its faults. A slow-burn first episode and a little exposition prevents this one from being further up this list, but the series does make an original contribution to its genre in that it's what Hare describes as a whydunit as opposed to a whodunit.
Mulligan, as always, is fantastic in the role, but a little bit more of a backstory for our protagonist wouldn't have gone amiss.
