Sorry, professor, but the start of fall semester means one thing: new television shows. With so many ending last year, keep an eye on these promising debuts.

“Gotham:” Sept. 22 on Fox

Those who have had a bad case of Gotham City blues since the Christopher Nolan trilogy ended in 2012 are probably eagerly anticipating the intense “Gotham.”

“Gotham” tells the story of a young James Gordon’s life and his rise to prominence before good ol’ Batman came along. With a relatively unfamiliar cast, this seems to be a show where celebrities won’t overpower the storyline. But to be fair, young Gordon is played by “Southland” star Ben McKenzie, and there’s going to be an appearance by Jada Pinkett Smith. Show creator and writer Bruno Heller is known for his creative episodes on “The Mentalist.” “Gotham” seems to bring fans so much of what they loved in the Batman trilogy: captivating characters, drama and hopefully a little humor.

“A to Z:” Oct. 2 on NBC

Viewers got a taste of Broadway treasure Cristin Milioti during her short time as the mom on “How I Met Your Mother.” The final season left me wanting to see more of her talent. Now, I’ll get to enjoy her as the co-star of “A to Z.”

This show follows young couple Andrew and Zelda from the start of their relationship to its final moments. The pilot episode was released on Hulu as a bit of a sneak peek before the show actually premieres. “A to Z” features Ben Feldman as Andrew. People may remember him as Michael from “Mad Men” or Fred on “Drop Dead Diva.” With these two sweethearts playing, well, sweethearts, “A to Z” is bound to be a nice combination of funny and romantic.

“Forever:” Sept. 23 on ABC

Every fall, there seems to be a new science fiction show that kills or crashes, and “Forever” looks to be the prior.

This show is about 200-year-old Dr. Henry Morgan (Ioan Gruffudd), who works in a New York City Morgue. Here’s the shocking part: He can’t die. While working in the morgue, Morgan tries to unlock the secret of his own immortality by using the deaths he comes across.

“Forever” includes Joel David Moore as Morgan’s assistant. While the show deals with death, the trailer shows many comedic moments. Interested in science fiction and comedy? This is your fall show.
