Marred by bad acting
This could have been amazing but suffers from truly across the board terrible acting. There is not one convincing performance in the entire film. Everyone sounds like they worked very hard to 'memorize their lines.' My guess is they relied on 'local talent' and it was not abundant. Specifics:
1) No one seems afraid. The teen doing face time should be losing it but is calm
2) The couple on the boat are described as 'a successful dentist and a powerful lawyer.' They both look 25 and chatter'Oh my God!' constantly, like teenagers.
3) The motherinlaw on the phone literally sounds as if she is reading the phonebook
4) Everyone with disgusting lesions acts like they have a sunburn
This was a fun premise but you'd be better off watching a B movie with a similar story like 'Humanoids from the Deep'
