You have to go into Siren with the right set of expectations, and what those are is perhaps surprising, but it's a crazy kind of fun, even if it's probably too unstable to last.
For the People is a curious Shondaland entry, and curious Shondaland entries don't generally fare well. There is something of a return to the early days of Grey's here though, but those days may be too far gone. Plus, it's largely laughable.
Roseanne was always a show that seemed to teeter on the edge of getting in its own way, but you didn't care because it was hilarious. The revival throws a lot more obstacles at itself, and it isn't as funny.
Deception is a show that won't necessarily grab you out of the gate, but if the overall writing and characters catch up to the spectacle it'll win over fans in droves.
