OK that's what if felt like to me. Right from the beginning the acting and the whole atmosphere of this film made it look like a late night porn film without the porn.
It was probably something to do with the actors who all looked like they had been drafted in from the set of Lucy does Dallas or Majorca or whatever (or whoever) Lucy is doing at the moment.
Once I got into it it wasn't bad actually. The story kind of hooked me and I was pleasantly surprised. Apart from the obviously low budget it was quite enjoyable to watch. It was like a whodunnit with a twist, the twist being the fact that nobody has been killed.
This is not the best film ever made but it kept my interest.
