Ok, reverse that logic. How many people really care that Wakanda was a monarchy? We had numerous issues of people sitting around spouting philosophical nonsense on how the monarchy sucks in Season 1 and people loved it (including you). Now, suddenly, diving into how this DRASTIC change in how Wakanda functions is now "how many people really care" and "boring."
Pick one.
If you are going to change a core concept of T'challa (being an absolute monarch) and Wakanda... you need to explore how that change actually affects things. Otherwise the story is useless. You can explore that within the confides of an action comic if you choose to. It doesn't have to be boring Coates yackity yack.
In fact, this story had numerous chances to show us what the differences is.
1. T'challa was called to a meeting with this council. He told them to F off, he has better **** to do.
2. T'challa shows up unannounced to a council meeting. Upon a member of the council practically begging him to check into something, he goes "eh, I got better **** to do, tell my mom" and leaves the country.
3. T'challa travels throughout the different regions of Wakanda unannounced and bossing everyone around, including the Doras he just let "have their freedom."
4. Jabari land councilwoman begs Ramonda to tell T'challa to save their leaders. Ramonda says they can't because of the council. T'challa arms them anyway and then shows up with a DAMN META ARMY into Azania all by himself to deal with the treat.
You could easily tell a story where T'challa wants to do something and can't because the council won't let him and he has to decide what to do. This story had numerous chances to show it. Instead, all it proved, by accident, is that Wakanda functions better when the monarch has absolute control in protecting the country and whoever he deems fit to be protected.
