Watched this yesterday afternoon.
I echo what others have said in that it's not very good, or at least it could have been so much better.
Visually quite nice in parts but I didn't care about anyone in it, the characterisation and dialog from the off seemed very weak and designed for morons to be able to understand, almost at "He didn't see me" Predator level.
As for the technology, just weird. As an example they have these little spherical things for mapping that seem to be capable of flying with no obvious propulsion, yet everyone has to plod around on the surface huffing and puffing or using (electric?) vehicles. Incongruous. And how can that squid thing get so big so quickly? What was it eating? Bonkers and at times cartoon juvenile stuff that requires you to either have none in the first place, or to totally suspend your critical faculties and any semblance of scientific reasoning.
While I wouldn't have walked out if I had seen it in the cinema, it was watchable, I'm certainly glad I didn't pay to see it and doubt I'd bother watching it again anytime.
Disappointing. I'd hoped (and been led to expect from the virals) for much better.
