The abilities of the people on this show are amazing, no doubt. But the show's format is gimmicky and over=exaggerated, which makes their talents seem tawdry. The show claims to investigate their powers "scientifically" but all I saw were a couple of lame attempts at measuring heart rate, reaction time, etc., with no depth of analysis. (Although the high-speed camera is often very cool, e.g. a samurai cutting in half a baseball pitched 90 mph at him, not unsheathing till the ball is pitched).
Let me give you an example: There was a guy on there who's called a "human crash test dummy." He actually puts himself behind the wheel during car crashes, because the dummies can only give you so much information. So he's putting his life on the line to help further the research on car crashes, ultimately helping save lives. He's been through over 900 car crashes, more than anyone else on the planet, and hasn't had a single major injury yet, not even whiplash. That's definitely amazing, but it falls flat when you start comparing him to a superhero. The voice over guy keeps hinting that he's "unbreakable" but it's nothing of the sort. He's just studied car crashes so thoroughly that he can design them to be safe while still giving meaningful data that you can't get from crash test dummies. The "scientific test" consists of hooking him up to an accelerometer and seeing how much G force he's subjected to during a crash. Ok.. how does that help explain what's going on? The only gesture they make towards an explanation is that he's trained himself to prepare for the G force just before it happens, which is not always an option in a car crash. Look, anyone can do this, but only he has the balls. He deserves TV time, for sure, but this show just cheapens his accomplishments.
In short: if you're into Guinness Book or Ripley's, you'll like it, but if you're expecting something as substantive as Mythbusters, you'll be disappointed. I fell into the latter category.
