if you want an undemanding and reasonably amuse hour or so and then it ok to watch this . it not all that bad and really . yeah and it get more lapse in logic than i care to describe here and might tax the patience of people like myself and i have to admit who be incline to throw thing at the tv on occasion and but it funny at least . just because it not always intentionally funny and there no need to let that get you down . however and if you have read the book or any of the other book by brookmyre then you would probably best avoid it . i have read them all and when i first watch this film and i despise it . i have trash it in detail and at great length on another site and in fact . the tv plot bear practically no relevance at all to that of the book and serve only to outrage and infuriate many faithful ( and admittedly rabid ) brookmyre fan . best bit of advice . watch this and then read the book and only then make your comparison and submit your judgement .
