Here is a simple and obvious way to tell how effective JW.TV is going to be:
In the past, how effective has religious TV been for you? Has watching religious TV made by moonies, evangelists, mormons or scientologists made you seriously reflect on spirituality? Has it ever made you do anything? Has it even come close?
For me, the answer is a resounding no. In my experience religious TV has always been a complete joke, even less effective by far than talks or books promoting a particular religion. I cannot put a finger on why this is the case but it just appears to be so.
Turning to the particular case of JW TV I don't even think they did a good job insofar as religious TV is concerned. What is their most important story? That they build a TV set in two months. Who exactly are going to be impressed by this information? Suppose scientology claimed to have build a TV set in a single month, would anyone give a crap?
The content was awfull; within three minutes we had both heard that the TV show was a trial yet god had helped them build the tv-set. This is both contradictory and cultish. I could not bother to watch all of it but it seems comprised of booring talks and was unecesarily bland and condescending: "what come after twelve....thirteeeeen!".
No doubt the quality will improve, but I still have a hard time imagining anyone who is not a JW would really choose to watch this type of show over other content freely available. I am also curious if even hard-core JWs will want to watch it, it seems like meeting/convention type content but without any of the social interaction or peer preasure.
It is going to make for great youtube material though.
