“Apart from a wasted C-plot, “Walk the Swine” sees The Muppets continuing on the same course correcting trajectory as “Pig Out.” That episode, perhaps more than the three that precede it, brimmed over with the sort of Muppety humor we expect from any narrative that revolved around them; what it lacked in forward momentum, it made up for by being funny, which felt like a godsend after the tragically mirthless “Bear Write Then Bear Left.” At this point, it might be wise to ask only for “funny” from The Muppets. The show so far hasn’t shown a great interest in either building up to or on anything, and instead has devoted itself to fostering its own sense of modern edginess.” (Via Paste Magazine.)
