From start to finish this is a lesson in how not to produce a TV thriller . It's easy to mock the hammy acting , which is by itself the worst you'll ever see in a mainstream TV drama on a major channel with a decent budget , but the " actors " are really let down by a truly appalling script , the dialogue seems to have been written by a small child who has no knowledge of police procedure or indeed human nature .
The main plot does not work in any way - a half witted yokel who is shown kidnapping a woman in front of her children , but maybe his brother did it ? He's also a yokel but with a completely different accent . But what really sets this apart for sheer awfulness are the subplots , Walker trying to teach himself computers , then his exwife who has a new boyfriend , who for no apparent reason turns into a foaming nutcase , then there's Walker's much younger brother who has never been mentioned before because he's the black sheep but of course his Ma still loves him . This character alone must rank as the most comically ( unintentional ) awful of all time in the history of British television ,kids in drama school please watch this " portrayal " and try to do better - if you can't , then give up .
The story eventually resolves itself , and the audience is mightily relieved , yet annoyed at wasting so much time . This isn't to say you shouldn't watch this ,you really should watch - it is simply so laughably bad ,whilst simultaneously portraying itself as good quality drama , you can feel better about yourself safe in the knowledge that on your worst day you could write a better script and stand out as the best actor in this . So bad , it's completely brilliant
