First let preface this with the fact that the shows probably an 8 but I'm giving it a 10 to boost the rating. This is easily the best paranormal investigating show out there, the methods are more realistic, it way less far fetched, and they aren't just fabricating encounters for added excitement. Some of the episodes are actually pretty slow which is a great thing because they're not just faking it, they're actually showing you what happened even if they didn't find anything. It's a crime it didn't get more than 2 seasons, and it's absurd that it has such a low rating. Ghost adventures and the other shows are nowhere near the level of ghost lab. Give it a shot you won't be disappointed.
