They are back for the final season. I found by accident the 1st episode this evening and it looks interesting. I cannot say more without spoiling it, so here you have the trailer, if you are not bored with the series yet.
We didn't know much about Chronicoms until the end of the last season. In S7 they appear to be the bad guys. Enoch has always acted as an ally of the S.H.I,E.L.D. Not the others. A war is on the way. But since the Chronicoms have to fight almost the entire team, the season has good chances to entertain us.
