I enjoyed this episode as it is the first time we see Quayle, an old nemesis that has a second chance to kill MacGyver. He does it well and boobytraps the mansion well, I think.
It was a little obvious that MacGyver would have to go for the power source as all of Quayle's boobytraps were electrical. However, MacGyver has a real hard challenge for the first time as Pete is mixed up in the mess, as MacGyver actually escaped the mansion and had to return to save him!
Now we have an enemy for MacGyver, like Batman - the Joker, Superman - Lex Luther etc. it makes it more interesting and we get to know Quayle's strategies. Overall good episode.
