Did anyone ever think that a movie review looked familiar, or reminded them quite closely of something else, hell Yea, happens all the time. but this really peaked my interest, the first thing that came to mind was the colour of the aliens, the bright blue, and then the bright red ones, then i started thinkin of apparent shape and size.

Did these guys get the idea for Skyline from Crysis

Dude, No they are not alike in anyway shape or form.

I didnt say they looked like the Crysis aliens I reffured to the colours, the large aliens and the small aliens and the colours.
A feeling ios not an exact science, nor was i intending an exact match.
I know the crysis aliens way too well, all of them.
this was just a feeling and an idea.
like i said the review peaked my interest
open your mind dude
