I rather enjoy Jeremiah. He's much more sociopathic, though, I'm partial to this kind of villain since he reminds me of guys like Ed Kemper. Intelligent, controlled, indifferent. It'll be an adjustment. A lot of folks here will perhaps just miss the unpredictable, psychopathic behaviour of Jerome. Jeremiah isn't fireworks, but if the write him correctly his character will have more depth.
Ordinarily I wouldn't think that Fox would can this show, however, they're dropping everything left, right and centre at the moment and viewership is everything. From what I understand, season 5 is sort of a reboot, so, it'd be disappointing if that weren't to happen. That being said, with Brooklyn nine nine being picked up a day after Fox cancelled it, I'm confident there'd be a big petition for it to be picked up elsewhere.
