Well, my lovely wife and I have been watching a few shows via DVD for the past couple months. Actually, there have only been 2 shows that we've seen this way - Grey's Anatomy and The Office. ( As an aside, I think this is a far superior way to view TV - no commercials, you get to watch them on your own schedule, it frees you from the addiction to TV to an extent, and, if you have the will to do so, you can censor them yourself.) However, after watching the first 2 seasons on Grey's Anatomy, I've had some mixed feelings about the show, and I think I will be much more careful about watching it in the future, if I do at all.
First of all, the show, which is about a group of surgical interns learning how to cut people open and fix them up and all their other life experiences, lacks any understanding that actions have consequences. The interns are constantly breaking the rules and cutting corners, and this in a business where life and death occur daily. Now, I realize that this is just entertainment, but entertainment often teaches us far more than books or classrooms. One intern even stops a man's life-sustaining heart treatment in order to make him worse so he could move up the donor list, only to have him die of some freak complication a day after he gets the new heart. While that intern, I've heard, gets booted out initially in the current season, I've also heard that she gets to come back. In addition, this sort of 2+2 does NOT equal 4 logic extends to their personal lives, where they are all sexually promiscuous and drunks.
The lack of integrity is bad, but the thing that Grey's Anatomy does that is so horrible is that it, through good storytelling and cool characters, makes the viewer start to want the things that the characters want, most of which are immoral things. This was pointed out to me by my wife, who said that the show makes her wish certain things would happen to/for the characters that she would never wish for a real person.
The best way I can illustrate this is with the following contrasting example - Grey's Anatomy, in the TV world, causes me to wish that Meredith and Derek, who is married to someone else, would become a couple, but in real life, I would never wish a marriage to end so a man could start an illicit relationship with a girlfriend. In fact, I would strongly counsel those people to stay apart and for the marriage to seek help, and I would pray for them and witness to them. The show so muddles things that the idea that there really is a right way to live life is gone.
So, I realize that there are probably some people here who do watch this show. I'm not saying you have to stop to be a Christian, but I am warning you to think about how you feel and think while watching any show. If the feelings and thoughts that are evoked are contrary to the truth of God, as revealed in the Bible, then you might need to stop watching. Sometimes, I wonder where the line is between being a person who will watch these sorts of things on TV for entertainment and being a person who would do them himself.
