FOX is obsessed with showing Jurassic Park 2: The Lost World. I swear it must be on at least every 3 months, usually filling in the slot of a show I was expecting to watch.
FX, I think anyway, is always playing Armagedon, seems it’s on at least every other day.
I see Ferris Buller’s Day Off on a lot, as well as the aforementioned Sixteen Candles, The Breakfast Club, and Pretty in Pink.
