I listened to the podcast, and while I agree with a lot of what was said, I can't agree with some of it. As bad as it was to fridge Lilah, I don't feel like it was really a betrayal of the characters to do that. Zeke is more than a little psychotic, and it's been set up for a while that he's not entirely trustworthy. Also, sometimes media doesn't have happy endings. We are not owed a happy ending for characters, and it's not a "screw you" to the audience to end in a tragedy. Moreover, I don't feel like the ending was a downer. Ethan went out a hero, even without the Mary Sue ending tacked on afterwards. It didn't wipe out years of comics any more than the The Amazing Spider-Man wiped out the previous three films. Those comics still exist.
Disagreement on the ending aside, there was another point: Buckley actually has written a female character who didn't exist to be a romantic interest for one of the male characters. Abby the game store customer was a rival for Ethan. Sure, she was a copy of someone else's design, but she was a named character who wasn't simply a romantic conquest.
