First off this is a flashback episode. That alone should tell you to skip it. But there's about half of the episode of new footage, and about 15 percent of interesting new footage. To start with a unknown attack is after someone up in this fishing spot, where Jack Dalton has gotten some land that might have gold. Early on they show, nope there's no gold but the crew (Jack, MacGyver, and Peter Thorton) decide to have some fun anyways, go fishing, camping and just generally pal around. The problem is they keep talking about things in the area and flashing back to the last time they were "in a mine" or "out to sea" or basically anything that has nothing to do with the episode. The problem is these flashbacks are measured in minutes, and usually not singular. If you've seen the previous episode you won't see anything new, and they are too long just to give you a taste. Including three very short glimpses of Murdoc episodes
The assassin later turns out to be Deborah, and finally a useful set of flashback appears, again though the flashback is in the multiple of minutes time frame.
The problem though is when Deborah is revealed the entire episode falls apart. Deborah at the end of the original episode works with MacGyver to take down the guy who hired her. Why then would she again attack MacGyver? This isn't answered, instead she talks about how she loved him and that's why she failed, and then she says maybe she has the same feeling but she's going to kill him anyways. If this sounds cheesy, then you're on the same page as I was.
The ending is the obvious, killer about to fall off the ledge, MacGyver as always tries to save them, they take a final swing at MacGyver, and die in the process. It's about as obvious as can be.
The bigger problem is this has all been done before in some format, we have a very weak MacGyverism that's barely explained, too many and too long flashbacks, out of character killer motivations, and a extremely weak episode for the final episode of the season. Overall it's lucky the series continued but I think it would have been better if this episode was canned instead of shown. It would suck to miss an hour of MacGyver, but after watching I'd like to request a refund of the 42 minutes that I watched.
