in some cases not enough rigor in their tests
That was the problem for me with Kari, Grant and Tory. Sometimes I think they actually failed to test the myth because of some issue with their setup. I wouldn't mind that if they used it to add discussion about what constitutes a real test, or maybe suggest some way that it still could possibly be true. Invariably, they would just claim that this is "totally busted!"
It's just annoying. It's like they don't want you watching the program if your standards are too high. Goddamn it, that's what science is about!
I can't expect them to be as good as Adam and Jamie - they've got a lot of experience in making things happen from working in special effects. Some of their setups are quite ingenious. But watching these other fools pretend to do the same thing is just sad sometimes.
And yeah, as people have been saying, the fluff factor is worse than ever. Those little acted out bits with silly music are horrendous. What a waste of time and effort. Just do the myths. Watching clips on youtube is far better than watching on TV.
