"iZombie" wrapped up last month and I have found it enjoyable. One thing I noticed was that since in this case, the central character, Liv was female, and so one of the main people out of the loop on what was really going on was (as in her zombieness), her ex-fiance Major. (Yes, his first name is Major.) (Also, spoilers ahead.)
So, in much of the paranormal stories there are characters who are out of the loop. This list usually starts out big, and dwindles as core characters are let in on the secret. What was semi-unusual, was that Major was not in on the secret. Now of course, it's understandable that Liv didn't sit down and say, so, hey, I know we love each other, but I'm a zombie now, and since we haven't actually officially promised in sickness and in health yet, now seems like a good time to call it quits. Now, let's face it, this is a dressed up version of, "it's for his own good". But, it was believable that he'd already unknowingly survived a number of encounters with zombies, maybe at least the red tape of the right ways to handle this would slow him down. And Major, in turn, didn't just decide to go in without a large amount of firepower. Sure, do I think it would have been, I don't know, eminently wiser to go with more people? Yes. But I had presented with reasons that Major thought this was important to him, and why he thought it needed to be stopped now. And that helped a lot. Of course he did not survive the encounter, technically.
So, it's hard to parse how much this is different due to the genders involved, but it certainly seemed like the viewers, at least in my corner of the internet, found Major's approach reasonable based on the information we had, and Liv and Ravi's choice fair based on their concerns. Which is in contrast to several shows where it's a girl outside the info. (And I have not forgotten Liv's roommate, but, her overlap with other zombies had been minimal.) Honestly, I think the largest difference is that "iZombie" had a short first season, so Major figured out the truth in half the time a normal (ex) love interest would have. I hope other shows take a look at this, because it was really fun to watch. Of course as a viewer I knew he would find out, would be in danger, they would wish they had told him sooner, but it moved at a pace that I was able to buy into why they were holding off.
