Just about the worst possible ending. Incoherent, muddled and unbelievable. A shame because the first two or three episodes were quite promising but the writers lost their nerve over the direction of the plot and it went downhill from there. Idris Elba's character seemed devoid of any common sense despite his supposed /expertise as a negotiator. The hijackers were a random set of amateurs, the police were incompetent beyond belief and let's draw a veil over the politicians and civil servants. If only someone in the production team had had the guts to say 'stop, this doesn't work' it might have been possible to rescue things but then again the acting was generally implausible and cliched.
