Josh & Co follow up reports of voices by experimenting with the echos from the surrounding hills and canyons. Since this provides a possible explaination for the reports, the reports are dismissed.

Josh and Co. hear footsteps, Ryder reports seeing movement, the Flir shows what could be a human figure, yet NO experimentation is done to see if actual footsteps would be heard, or if an actual human would appear on the Flir as was shown . 

Jay and Grants' expertise boils down to " Yup, it looks like a person – you say no one was around ?  – then we declare it paranormal and amazing "

Are we supposed to believe that Israel leaves this important area completely abandoned at night ?

I have no problem with the "fun" or tourist aspects of the show, although the beach scenes went a bit long in this case . 

As far as filling up the hour, we have to believe that they showed us the most entertaining parts of the investigation, so more time would have simply been more  images of green people walking between anonymous piles of green rocks.

My only suggestion would have been taking the tram and using the extra daylight to show us some of the area up top before dark.  Not sure what the hike up the hill was meant to show us or what good it did for them besides a check mark in Josh's "things to do" list. Perhaps in their show menu they need to incude somthing physicallly challenging, like the cave exploration ?

I have a suspicion that Josh puts Jay and Grant in the same catagory as the pub owner with the Leprechaun skeleton – he knows they will not let anyone else check their evidence – it would be bad luck.
