I am extremely doubtful that the A&E 2-night version of The Andromeda Strain will top the original 1971 version. Here's a pretty good old trailer which indicates the sophisticated level of cinematic story-telling for this sci-fi thriller.
A further great document of the original book and movie by Michael Crichton puts the original story in context. Fears about biological warfare in the Vietnam War-era, coupled with a young 20-something author created a lot of media buzz for the original film.
Bonus points for having the very fine Canadian actor Kate Reid in perhaps her most famous role, Dr. Ruth Leavitt.
In case you haven't figured it out by now, I consider this movie as a very fine work of cinema, worth having in your personal collection.
