Are you sure it's the last season? If it is, I think I can stick with it.
I think by Season 3, I didn't feel like it should even be called MacGyver anymore. It's strange - the hook of the show is that Mac jury-rigs solutions to survive and/or save the day, usually using household objects or chemicals. But I think the show never found a way to embrace it. In the original, Mac was usually on his own so he would voice-over the science behind what he was doing. In the new show, it felt like they were too rushed to explain it. Sometimes they would flash an overlay of diagrams and equations, but it felt like they were constantly searching for a way to include it in the narrative. In the modern adaptation, I guess all action/adventure procedurals have to be teams now. But I think that made it more vanilla - now there's a fighty guy(now gal) and a computer "hacker" who pulls impossible magic. I didn't really like the "I wanna be a spy because spying is fun" tone, and thought it was ridiculous that they would reprimand Mac for choosing not to die and "improvising." It felt like such a horrible distortion of what the original was.
Then I went back and watched a couple seasons of the original. Oh man, that show was goofy. Maybe I can cut the current show a little slack.
Anyway, I'd been on the verge of quitting for a long time. I finally decided to quit after Season 3. Then I found out Terry Matalas was taking over as show runner. I LOVED 12 Monkeys, so I'm curious what he'll do with Season 4. So ooooookay, I'm back in for a bit. I felt like the last episode this season with the planes was starting to get better about explaining Mac's gadgets. I guess narratively they had a kid so they had an excuse to explain stuff.
