If anything, this series goes to prove that you cannot just stick a few well known actors into a show and expect a hit....In fact in cases like this it is a big miss.
The actually concept is tired and old, but does work when written well, just sadly this is very poorly written. The acting is in most parts really bad and you could have probably cut down the characters by half and not missed any and made a better show.
I understand the point is to try and build/weave individuals into the story to create an air of mystery and more questions as to 'who dunnit', but whilst I didn't guess the ending, which is usually a good thing, by the time it came I just didn't care...And that is the biggest problem, the obnoxious nature of all the characters meant that I just did not buy into the series from the outset!
If, as a previous reviewer has pointed out, it had been done over a couple of episodes rather than 4, it maybe would have been more suspenseful, but alas, it wasnt and errr it wasnt.
In my opinion, tv series as a whole have got a 'netflix' complex, they want to build a story. but at the same time they want the conclusion far quicker than the build up allows. It is not uncommon to see ITV, BBC One, and now 5 serialising shows over a week, but it just doesn't work, you only have to look at recent TV successes (Line of Duty, Game of Thrones etc) to know that to build tension, you either go week by week, or to give people a fix, you drop it all at once, this whole 4-5 night approach doesn't work and invariably leads to making the show too long and too boring to satiate a viewers appetite!
