Because schedules exist. How do you make sure all your actors and directors and sets are available when you have no idea when the scripts will be done? Not to mention how do you advertise something you have no idea when it will be done?
I’ve been a Tick fan since the comic book days. We just kind of got used to “maybe a month, maybe 2, maybe 3, maybe...” The publisher only put up with it because it was their most popular title.
Then came the Fox animated series, and Fox got to deal with it. Then they were silly enough to sign on for a live action show. And they canceled that after 1 season. Then Amazon jumped in and it took them 4 years to get 22 episodes. Now part of that was Amazon’s fault because they were playing around with making premier episodes of stuff and not greenlighting full seasons until months later. But even then it took more than a year between each group.
Edlund’s brilliant. And a nice guy from everything I’ve seen. But he isn’t professional, and making a multi-million dollar project dependent on him is generally a mistake. Though the results are brilliant when he finally finishes.
