Perhaps a week off is what it takes for "Gotham" to right itself. After returning from winter break with a rather mediocre episode, the show then took another week off and came back in top form.
Never once did the show convince me that Falcone was so enraptured with Liza that he'd quit his life for her, nor did it ever show me Fish feeling anything but contempt for Falcone.
It seems that Gotham wants to move quickly from its stories and bad guys, but I wish that we would get a little longer to go in depth with some of the characters. Give them time to grow, especially the enemies that Jim must face.
The interplay between Doman and Smith in particular is wonderful; it's weighty, hammy, and nuanced all at once, not only giving us an explosive confrontation, but also hinting at a the long history between the two.
