Piss-poor TV

Why can't the networks put on any good TV on saturday nights or sundays?!
So I get home from snowboarding (which was fantastic, thanks for asking) around 8:30pm on saturday night. I'm too wiped out to do anything except settle in for some TV and a couple beers. What do I get? Crap. Where are the days of USA and TNT playing solid "Guy Movies" to entertain those of us that are home watching TV on a saturday night? I want to see something with car chases, explosions, guns, fist-fights.
I wound up flipping aimlessly for a couple hours while surfing the 'net until my roommate came home. Then I just gave her and her fiance the remote and let them struggle for awhile.
Man, onec college football ends, so does all the good weekend TV. The networks know they no longer have any real competition for your time, so they'll just make you watch whatever garbage they feel like showing. What are you going to do, watch Lifetime?!
