Blast my big screen??? Don't think so!
Seriously. While there are many horrible things on television, and it is perfectly in one's liberty to have one, or not to have one, television can be a fun source of entertainment. We don't watch a whole lot of tv, but there are certain show we watch regularly when in season (Lost, 24, and Heroes). We also love renting a good movie on the weekend.
Christians should certainly guard what they watch, but I think that there are shows that are not too bad at the same time.
BTW, we do not have cable either. Just an antenna.
