Well, I hear that Sci-Fi has been pushing for more action, which is been causing alot of supposedly "set up" scares, which is the main reason you don't see as many house investigations as in previous years. I also heard that Sci-Fi told Jay and Grant that they wanted a better looking girl for the show, and they chose Kris for them. As you can see here, she's been an actress before they put her on the show
http://www.imdb.com/name/nm1366043/ She even has a cameo in the new movie 21.
Brian Harnois explained how he was asked to leave the cast because they weren't Ghost hunting, they were rating hunting. He joined GHI which has no affiliation with taps which many people think they do along with Andy and Donna. They focus more on the paranormal which the show has lost track of since it's way over produced. These people were in it for the research, not the money like it has come to. There have been many other experiences where Jason and Grant are arrogant when you meet them and other stories which make it seem that Jay and Grant have HUGE egos. I've read this on numerous sites, i've also read different stories too which favor them. But Kris just didn't seem right from the beggining, and I tend to believe that story more than others.
HAHAHA.. sorry I had to laugh at this.
1) Kris has been a friend of the TAPS team for quite awhile before she was asked to join in on the investigations. Considering the numbers they had recently lost (Donna, Brian, Andy, and Dustin) for a variety of reasons, it should be expected that they would have to bring someone in. Plus, really, does it matter what her occupation is? An actress can have just as much investigation skill and just as much curiousity into the paranormal as anyone.
2) You don't see as many house investigations for a multiple of reasons. First, remember they do more investigations then we will ever see on TV and I would bet that many people don't want the whole crew in their homes AND don't want to known as the crazy "haunted" people when the show airs. Second, as the TAPS name has grown, they are being allowed to investigate places with big names and getting new oppertunities. Wright-Patterson anyone?
3) How can GHI have no affiliation with TAPS when it was Jason and Grant who helped put the team together led by a TAPS family member? Also, if it wasn't TAPS why would information on their trips and investigations be on the official web site?
4) I don't care why Brian left, I'm just happy he did. He was dead weight on more then one occasion (like whith his girlfriend situation) and only caused rifts within the TAPS family.
5) Everything I have ever seen on Jason and Grant show them to be great guys with great personalities. They can be very protective of their work, reputation, the team, and their investigations. This I guess can be seen as arrogant but really it's their life long passion.
6) As another poster mentioned, there are groups out there who don't like TAPS due to the light TAPS has shed on the amount of faked evidence out there. Some groups, who may have had people fooled before, are now finding that people are looking closer at their evidence then they would like. This has caused some to just flat out fail, though there are those that seem to just keep bringing us photoshopped evidence.
Yes, I am a TAPS supporter, though I am not a TAPS family member. I do a bit of investigating of my own but nothing to the extent that TAPS does as I don't have the money to invest into the equipment. I spend quite a bit of my time on their boards with others, both believers and skeptics.
