The Holiday viewers all have the same complaint as Izzy’s killer is revealed in dramatic finale

THE Holiday viewers all have the same complaint after Izzy's killer was revealed in a dramatic finale.

The four part Channel 5 drama concluded tonight after airing across four consecutive evenings.

The plot followed policewoman Kate and her family as they holidayed in Malta with her uni friends and their loved ones.

However, the trip was tense from the start as Kate (Jill Halfpenny) suspected husband Sean of having an affair with one of her friends.

Things took a more tragic turn in Thursday's penultimate episode when Kate's single friend Izzy - who she believed to be Sean's mystery woman - was found dead at the bottom of a cliff following a fire in woodland near their villa.

The final episode was quick to reveal answers to viewers after the build up of the past three nights, with Sean coming clean about who 'CoralGirl' really was.

It turned out to be Kate's friend Jenny, however, they were not having an affair but in fact were covering up an incident which had left a teenager called Alex in hospital just days before their holiday.

Sean told Kate how he had spotted Jenny's car speeding off before discovering it was her troubled son Jake who had been driving, and he had acted upon Kate's daughter Lucy's upset when Alex sent a video of her performing a sex act on him around the school.

Now Alex was dead and Sean and Jenny were desperately trying to figure out what to do, with Jenny determined to protect her son at all costs.

Kate barely had time to discuss what had happened with Lucy - who had sent Jake an audio message asking him to kill Alex in her upset state - before little Odette came in and revealed it had been Jenny who had caused Izzy to fall off the cliff edge.

The couple then realised Jenny had taken their son Danny back to the spot and ran to his aid, only to find a distraught Jenny holding him close to the edge and pleading with Kate not to tell the police about her son, while also insisting Izzy's death was an accident.

Thankfully Kate was able to grab hold of Danny and the action swiftly returned back to the UK where Kate and her family attended Izzy's funeral.

It was revealed that Jake had checked into a facility to get help with his mental health, while Jenny had confessed to Izzy's death, but with diminished responsibility.

One further twist was to come, however, as ahead of her first day back at work, police woman Kate told Lucy she was going to tell her bosses at the station about what she knew, and Lucy would be able to then live her life knowing she had done the right thing.

But the teen dropped a further bombshell by revealing she had been in the car with Jake when he suddenly swerved into Alex and knocked him over, so if her mum told her bosses about Jake, he would then reveal she was with him.

A devastated Kate was then seen sobbing in the bathroom before deleting the audio she had of Lucy and then smashing her phone into the mirror, seemingly going against her moral compass to protect her daughter.

Following the conclusion of the four part series, viewers took to Twitter to all complain about the same thing.

One wrote: "So Izzy died for no reason"

Another added: "Jenny killed Izzy… Because Jake said he told Izzy everything about the killing of Alex. Meh."

A third tweeted: "Nothing in the 3 episodes beforehand made any sense…even with the hints of an apparent affair….

"Now Jenny has completely lost her mind in the space of 20 minutes."
