As a pop culture writer who's spent a lot of time thinking about ensemble comedies, I say the difference between Ghosts Season 4, Episode 21 ("Kyle") and classic "bridges" fare lies in that beautiful middle space between emotional work and jugdish ghost humor. The introduction of Kyle (Ben Feldman), a new ghost-seer, brings fresh tension to the Sam and Jay dynamic, bringing out their insecurities and also giving a relatable layer to ghost-human interactions that can feel as chaotic in real life. The Sasappis-Joan subplot, given some awkward charm by Roman Zaragoza, provides a touch of sweet sorrow and vulnerability that contrasts with the absurd humor generated by Kyle, wherever he may end up. Structurally, the episode does a fine job interlacing these storylines, with snappy, character-based humor that allows for comedic and emotional payoffs without one overshadowing the other.
