Spoilers for 'MacGyver' Season 4 Episode 9 'Code + Artemis + Nuclear + N3mesis'.

Another killer episode of 'MacGyver' Season 4 has landed and it's easily one of the best in the season so far. Focusing on Riley Davis (Tristin Mays) and Angus "Mac" MacGyver (Lucas Till), the episode balanced action and drama to deliver a solid story that appears to be a hit with fans.

Quite a few of the show's fans have taken to Twitter to discuss their opinions on the episode and the general consensus is overwhelmingly positive. Here's what fans have been saying:

"Tonight's episode is definitely a favorite of not only the season but the series so far," one fan wrote on Twitter. "I saw two parallels to older episodes, and everything was just done so well. Kudos to the cast and crew for a fantastic job tonight!"

Another fan wrote, "Amazing!!! Ready for next Friday!! So Good!!"

"I have tears, but what a Great episode," another fan tweeted. "You knocked it out of the park again. Thank you to all of the writers, cast, crew, and production team of #MacGyver"

"Ok after processing all the events from this episode I’m 100% sure this was the best episode from this season, I know I said that last week but can you blame me?" One fan declared. "And it was an emotional roller coast, all Riley's flashbacks were INCREDIBLE get to know more about her? amazing.

"And that ending?" They continued in the same thread "I said Mac should see a therapist but now I NEED to see one, so who's gonna pay????  Seriously, @lucastill and @Trizzio were AMAZING this episode, great work! Ready for next week's episode!"

As amazing as the episode was, fans are still pretty heartbroken over the death of James MacGyver / Oversight (Tate Donovan) and it's not a loss that will be forgotten easily.  

One fan wrote, "Truly superb performance from the @MacGyverCBS @MacGyverWriters cast and team tonight; the void left by Mac's dad is heartbreaking, the world would be so much better off with more than one MacGyver."
