This is rather an odd series to own on DVD. As with Ghost Hunters, GHI's episodes are edited together to constantly try to shock and surprise the audience with numerous set-ups and reveals. Once all the evidence (or lack thereof) has been revealed, there really isn't much to be gained from a repeat viewing, which makes it tough for me to recommend purchasing this DVD set. A first-time viewer would be better off catching a repeat episode on the SyFy Channel. There's little to no continuity between episodes, so they can be easily viewed in any order.
For viewers who enjoy the show and have already seen these episodes on television, this DVD set offers up very little extra material to entice a purchase. The case feels cheap and includes no printed material inside, just the three DVD discs. The only bonus material on the discs consists of a few scenes edited out of each episode, none of which offer anything new in terms of paranormal evidence, but instead reveal some behind-the-scenes moments and additional information about some of the locations. Some of the footage captures the investigators joking around with one another playfully and honestly I wish some of that could have made it into the actual show. These clips show a far more relaxed Demarest, and perhaps it wouldn't have taken me so long to get accustomed to him as a host if I had been able to see these moments earlier.
If you're already a fan of Ghost Hunters, then Ghost Hunters International is a good source of "more of the same." But, chances are, if you are already a fan of Ghost Hunters then you've already seen at least one episode of GHI and have formed your own opinion. If you've never seen a single episode of either and are interested in a good paranormal investigative show, I'd recommend checking out the original Ghost Hunters series first before GHI.
