It was so far ahead of its time that critics just didn't get it because the world they were satirizing was still about a decade away. (Instagram, fame, product placement, fanboyism...)
Also, bonus answer. The Big Hit. Because fuck it. Lou Diamond Phillips knew exactly what kind of shclock movie he was in and chewed the scenery fantastically.
