Review of The Proof is Out There

I enjoy watching this show, but I feel like if they're doing a story on something that may be difficult to "prove" or distinguish between fact or fake the do not do enough investigation. If the subject is easy to come up with an explanation for, they do a good job discussing what the phenomenon actually is. But, with things that don't have an actual explanation right away they just write off as "unexplained phenomenon" or stop investigating and just SAY it can be explained. I wish they would continue investigations on harder to prove things until they get an actual explanation, or at least narrow it down to a few choices.
