While the superhero TV show market seems to be saturated now, in the 90s, there was one show that really stood out. Even if you didn't love superheroes, Lois & Clark: The New Adventures of Superman was just an awesome show.
When the show started in 1993, people didn't know what to expect. Superman had been away from the screen for a while and they did not know how this new angle would work. While Lois & Clark was a superhero show, it was also a romantic adventure and appealed to a wide range of audiences.
People loved Lois Lane, but her judgement was questionable. She falls in love with Superman, but not Clark Kent, leading to a lot of issues because Clark is very obviously in love with her. She ends up getting engaged to Lex Luther (the main villain in the show) but at the wedding she realized her feelings for Clark and leaves Luther at the alter.
Eventually, after many false starts and a clone wedding, the two characters got married, but even that wasn't enough to save the series. The show was supposed to go into season five, but when Teri Hatcher (Lois) became pregnant they didn't want to write it into the show, so they cancelled it.
The show ended on a bit of a cliffhanger with a random child turning up with a note saying that they were responsible for them now. Kind of a big thing to just leave without answers, isn't it?
