I found and find Dead famous to be a top show. It's very different from the usual paranormal shows you see where everyone screams at the slightest sound. Gail's sceptical attitude mixed with Chris' ability and outlook certainly make compelling viewing through their disagreement or even if Gail thinks something is amiss - its good to see.
I'm glad this show hasn't followed the similar routes in which other shows follow just to keep gullible viewers watching. Recently an episode was displayed where not a great deal happened and other than one comical moment that was it - Most shows would of just faked something. But not dead famous. This is why I feel it is refreshing to see.
Chris is seriously enthusiastic about his paranormal research rather than in it for the bucks and Gail is quite a brave young lady for taking on what she does. Also having a "target spirit" is quite intriguing, Chances of finding that spirit may be very slim but it certainly makes i more interesting than just hitting a location and hoping to find SOMEONE, and that be the end of it.
I'm afraid I have no idea why anybody would have a negative view of this show - It's very appealing on many many different views. With brief history of locations, history and talks about the celebrity who is being researched and of course the paranormal aspect of the show. Not to mention the lovely view for both the men and the ladies ;)
