You could easily argue Halo's influence stems from "Campbell's "Who Goes There"/ Carpenter's "The Thing" due to the Flood and their similarities. Inspiration typically doesn't draw from one source specifically.

I still find issue with saying it is the bottle neck as that discredits a majority of films that came before it. Like: Night of the Living Dead and The Exorcist both of which also make it into numerous top ten lists and seems more than a likely stepping point for zombie movies and possession movies (despite not being the first zombie/possession movie ever).
