OT - Good sci fi TV shows?

late 80's/early 90's they did a remake of war of the worlds for holloween night. they did it as if the earth was being invaded similiar to the original orson wells radio play. it had actual news people portraying themselves.
ufo enters atmosphere and is shot down. aliens respond by sending a asteroid on collision with earth. space base missiles are used to destroy asteroid at Last minute. while everyone is congratulating themselves they pan to norads space tracking screen and it shows hundreds of asteroids on collision course. turns out the aliens were friendly until we shot down the ufo. there were lots of "special reports" during the program as if they reporting on a ufo crash and the followup investigation. it was enjoyable. i would have liked it better if it was actually on multiple channels.
