I'm not shitting on it, and I strongly doubt it is the only show. They also didn't follow the comics most of the time so making it a big deal for this one event, where they also killed off another character that was on a semi interesting arc, is a silly thing to focus on.
Killing off main characters can be a good thing, but the show just didn't have any remaining compelling character arcs once they killed off the last thing that gave any reason for living to introduce yet another 'humans are the real monsters' villain.
