It was fine when they weren't on the first few seasons. Then, the show explored a lot of urban myths and, of course, changed the format as the show became more popular. After a while, though, it felt like Kari, Grant, and Tori were taking up the lion's share of the show, with Jamie and Adam as bookends and the five weren't interacting as much as they were when the Build Team were first brought on, I thought. The material was drying up by the time the Build Team was let go, though, and there were only so many stories about explosions, guns, things exploding, and shooting things I could take.
