Not being of any Christian beliefs, myself - This vintage SyFy story (written in 1955 by John Wyndham) completely lost my interest once this unwelcome element of religion was worked into the plot-line where it, unfortunately, prevailed right through to the bitter end.
IMO - SyFy and Christianity make for a terrible pairing in any work of fiction. These two subjects are, pretty much, contradictory in nature. And, with that said - I totally resented author, Wyndham for trying to force Christianity down my throat with this nonsensical story of his. I really do.
