Hmm, I dunno. "Returns from war?" I suppose there's some precedent for that in the original, since the first season established that he'd been on a bomb defusing team in the Vietnam War. But I don't want to lose the idea of MacGyver as someone who refuses to use a gun. I suppose it's possible he could've been at war in a noncombatant capacity, but it remains to be seen.
And the idea of a "clandestine" Phoenix Foundation bugs me. It's like they're trying to conflate the Foundation with the DXS, the intelligence agency Mac and Pete worked for in the first season. I prefer the idea of Phoenix as an openly philanthropic think tank, using Science to save the world and fight poverty and hunger and aid law enforcement and so on. And losing Pete Thornton and giving Mac a partner/team... I dunno. Part of the charm of the original was that Mac was a lone hero who tended to make friends as he went and had an ever-growing supporting cast of oddball allies, often ones who drove him crazy, like Jack Dalton and Penny Parker. I wonder if we'll see updated versions of them, or of Mac's archnemesis Murdoc. (Ooh, how about getting Mark Sheppard to play his father's character Dr. Zito?)
Overall, it seems a little self-conscious about "Hey, look how MacGyver we are!" Like, they took the idea of the famous mullet and went twice as long. And the bit at the end there, "Anyone got any bubblegum, wink wink nudge nudge?" Trying too hard. It seems they've embraced and leaned heavily on the surface elements that everyone recognizes, but not bothered to stay very true to the more in-depth elements of the series. (Cute having the "V" in the logo be a Swiss Army knife, though.)
