The following article is my own honest opinion. If you disagree, that's totally fine.
Welcome to a city where evil rules with an iron fist. Where hope is fleeting and few. Even where it's police force is corrupted. A city where absolutely no one is safe. Welcome to Hell. Welcome to Gotham City. Gotham is such a good show. It's an interestingly different take on the Batman universe. The characters are unforgettably unique (except Fish Mooney). And Gotham rightly sets up what the atmosphere of what Batman needs to be. Let me explain.
Gotham is flat out an interestingly different take on the Batman universe. That's because it's literally life before Batman. In this artistic interpretation, the world famous vigilante who doesn't take nonsense from criminals and psychopaths is scared twelve year old boy. Yeah, let that sink in. There's no batmobile. There's no cape or cowl. And there is definitely no trace of the bat-signal or utility belt. It's because this show isn't centered on Bruce Wayne. What makes Gotham so unique is that we see the infamous city through the eyes of one of Batman's greatest allies. Jim Gordon (Ben McKenzie) arrives in Gotham City hellbent on keeping the streets clean and safe from sociopaths. And makes the ultimate promise to catch the Wayne's killer. Gordon is accompanied by his colleague, Harvey Bullock, a crooked lackadaisical detective. In their crusade for justice, they encounter the people who are destined to become Batman's rogues. Such as Richard Sionis (Black Mask), Oswald Cobblepot (Penguin), Dr. Hugo Strange, and much more. Gang wars erupt. Bullets are shot. Allies betray each other, while much blood is shed in this dark, perilous city. Gotham essentially is a crime drama for adults. So this show really isn't really targeted towards whole families. This is due to all of the gang violence, severing of limbs, and characters with sociopathic personalities.
The characters in Gotham (except Fish Mooney) are all uniquely memorable. I'll just explain my favorite three. As we discussed before we have Jim Gordon (Ben McKenzie) , the main protagonist. He's a young detective who is by-the-book. However Jim has repeatedly cross the line to take down crime. Jim solves mysteries with his colleague, Harvey Bullock (Donal Logue), while working around the corrupted lawmen and gangs. In Gotham, Bruce Wayne (David Mazouz) is a young twelve year old boy who struggles to rise from the ashes of his parents' murder. He's hurt and flat out vulnerable. Bruce is naive about the criminal world, but already has the heart of Batman. Bruce is protected and raised by Alfred Pennyworth (Sean Pertwee). In Gotham, we see a different Alfred than what we see in the movies. This Alfred is a more gritty and less all-knowing. In this show, Alfred as a character is seen more vulnerable because he has no experience in raising a child, but still loves Bruce. We actually see Alfred fight, which is different compared to what Alfred is seen doing in all of the Batman films.
Ultimately, Gotham correctly establishes what the Batman universe should be. Personally, I really detest it when Batman is shown as campy. Batman is not a campy character. This show is one mood: eerie. So, Gotham is filmed in different parts of New York City along with visual editing to make it appear as the cloudy, dark and grey home of Batman. If you are a fan of Batman, then I highly recommend watching Gotham. It's on Monday nights at 8 PM on Fox. If you want to catch up the first full season is streaming on Netflix.
