It wasn't too bad for a TV programme...
For me the interesting bit was a comment by one of the searchers, near the end, where she said that (paraphrasing, IIRC) while he had loads of hours, most of his well publicised flying was substantially supported by other people and he wasn't experienced as a solo pilot in mountain conditions.
This makes the mountain wave / turbulence explanation much more believable. I think a lot of people would not accept it because all they saw were his 100,000 or whatever hours so "he must have been a brilliant pilot".
I also cannot believe he would have walked (or crawled) out of wreckage of which the biggest piece was about 2ft long.
