All valid points. But this is a TV show. Not real life. Production was done as best as it could back in 1985 for a series. Were there mistakes / contradictions? Of course! Lee Zlotoff created the show. Not Sherlock Holmes. And for what it's worth, he did a sterling job.
I think MacGyver was supposed to be about expressing that a hero could do all these miracluous things without having to pick up a gun a shoot his enemies. I think that it also tries to show that in life, answers are always there. You just ned to know where to look.
It represented a positive look on any scenario and always left room for optimism. This is why a show like Mac was so cool. We watch it now and it is a little cheesy. But it also is an almost 30 year old show. Still there are some amazing episodes that i recall to this day. As for watching them, some still holp up!
Things to blame on Lee & Mac:
Thanks to them, I now always use a Swiss Army Knife for things i need to fix.
Thanks to them, I try to live a alcohol free & smoke free life, just like Mac.
Thanks to them, I love jeeps!
And thanks to them, I love the great outdoors!
So I blame MacGyver!
PS! I still love the pilot! My favorite episode, next to The Human Factor & The Wish Child.
