Having watched how Season 4 kicks off, I can say viewers should absolutely expect the Fox drama to keep the atmosphere as dark and demented as ever.
Not all characters will return, of course (even though this is Gotham), but the ones that are sticking around are making up for any absences.
Few TV shows have ever gotten as bizarre as Gotham did during its first three seasons, with its fabulously over-the-top criminal underworld, full of larger-than-life characters and performances.
