In light of the Sokovia Accords, and with Hydra obliterated, S.H.I.E.L.D. has been legitimatized again and no longer needs to operate in the shadows. Since the world presumes that Coulson is
dead, the organization needed a new Director to be the face of the organization. Coulson finds himself back in the role as an agent and teamed with Mack, and together they are tasked with tracking down and confirming the presence of Inhumans.

Critic Reviews For Marvel'S Agents Of S.H.I.E.L.D. Season 4

“The series often turns on a dime, but the viewer never feels whiplash. An impressive accomplishment given the multitude of times this show could have easily veered off the rails.” – Geoff Miller, Paste Magazine

" Marvel's Agents of S.H.I.E.L.D. opened Season 4 with the introduction of a well-publicized new threat – the hot-headed, vengeance-seeking Ghost Rider – but closed its premiere with a second, equally ominous twist." – Matt Webb Mitovich , TV Line

" After setting up chess pieces all season long, this episode finally brought together the season's two disparate strands: Ghost Rider's hellish vengeance spree and AIDA's toying with artificial life." – Christian Holub , Entertainment We­ekly

" If anything, as far as I'm concerned, the show is back on track overall, after a slightly off-kilter first half of the season, marred by splitting up the team too much for too long and an overtly dour tone." – Mark Trammell , TV Equals
