I think my only problem is that he is touting it as a survival programme, and therefore he should show the correct way of doing things and that's it. You should never teach something the wrong way, it causes confusion and doubt.
If he had the metal mug all along, why did he not boil the water in the first place? Why did he even attempt to race through the mangrove swamp? If he was trying to survive, he would be trying to conserve as much energy as possible, he doesn't know how far he has to travel and what his food supply is gonna be like, so why try to push through mangrove swamps which are notoriously difficult to traverse?
I saw straight away how he could have recovered most if not all of his parachute and the rope, why didn't he? Maybe he only used the parachute insertion as a means of getting on the ground and wanted to make it look like somebody who had just got lost in the jungle so I can deal with that. And I have no problem with his camera crew tagging along, I doubt they roughed it like Bear did but then why should they?
For the record, although I have no doubt of Mears' knowledge and skills, I sometimes get the feeling he is doing something for the first time, or he has done it a couple of times before the camera starts to roll. I can't think of anything off the top of my head, it's just a feeling sometimes and I got it more on his bushcraft series. I just think sometimes he has read it in a book, picked up his kit and shouted "ACTION!!" to the camera crew!
Saying that, I prefer his style of presenting, he is calmer and more relaxed in his enviornment and he doesn't show us the wrong way of doing things. I really cannot believe that Bear took a swig from that water, it was like he wanted to get the squits to prove a point!
