Is this Real or Propaganda?

I'm still hearing about this "Heaven is for Real" propaganda from people. Now, on the rise is the "90 Minutes in Heaven" that recounts the story of a pastor who was "dead" for 90 minutes and saw the "Pearly Gates". 

Personally I have problems with these kind of stories and the millions they make off of them. First, it goes beyond any true doctrine that should be taught. Secondly, it gives people "false hope". Lastly, I truly feel that it's lies that are being taught to bring up more "feel good" religiosity. 

I've researched many of these stories. The "Heaven is for Real" story was finally made right by the boy who claimed he was put up to it by his pastor dad. The problem I have with this "90 Minutes in Heaven" story is that there are too many circumstances that surround this story that doesn't make sense. Don Piper was on his way back from a Baptist Convention when the wreck happened and thus declared dead in 1989; for 90 minutes! If you are dead for 90 minutes, you are dead! If you are truly "clinically" dead for 90 minutes body organs to include the brain begin to truly shut down. You will truly be dead and will not live to tell the story. Also, if you see Heaven, you are there to stay. He wrote his book and first publicized in 2004 (after the event happened six years earlier) which made its way to a recent movie format. If he was going to a Baptist Convention, in my mind he was a Baptist minister right? He was also "exiled" from many people in certain circles. However, now he does much of his ministry in the Pentecostal churches. He is even a pastor in a Pentecostal church. In my mind, I think the only denomination that would truly accept this story is the more charismatic religions. I mean I could go on and on about this! 

Now, that I have stated my opinion about this, what is your opinion? Should we as Christ's ministers leave this alone because as Christ said, "if they aren't against us, they are for us (paraphrased)." Finally, is this kind of propaganda truly necessary to provide hope to the faithless that Heaven is for Real? 

I thought faith consisted more of seeing or hearing such stories as this. "You have faith because you have seen, but better are those who have not seen and have faith". 

Ok, begin with your comments!
