Noel Murray had a more mixed reaction, giving the episode a rating of C+ and criticizing lead guest actor Cameron Monaghan, "In this role, he was a drag, playing 'rebellious teen' in a stock, wooden way, with no extra layers. Also, nobody—not even Joshua Jackson, whom I've come to appreciate more as an actor over the run of this show—could make the 'My mind is being controlled!' scenes look anything other than goofy." Murray also said, "Yet for all my griping, I was quite taken with the theme of this episode, and the motifs that writers Robert Chiappetta and Glen Whitman and director Joe Chappelle used to support it. From the tinfoil Peter Pan hats that Walter and Astrid wear to Tyler popping the medication that grants him his powers out of a Pez dispenser, there's a lot in 'Of Human Action' about childish things." Ramsey Isler from IGN graded the episode 8.0/10, explaining that despite it being a "standalone" episode, it was "a high-intensity, action-filled tale that kept the adrenaline flowing. Fringe is usually more of a cerebral show, but there's nothing wrong with appealing to our love of action every now and then". Also positive was Chanel Reeder of Newsarama, who believed Fringe "totally deliver[ed] in its most recent episode. The twists are back, along with the dramatic high intensity moments that the show is known for." Reeder praised the plot twist of Tyler being the mind controller, and was pleased with the increased presence of Massive Dynamic.
