I would say that BP2 was very realistic in the manner of "Oh shit, shit happens what do I do when I'm taking out of my comfort zone?" more so than any other superhero movie next to Spider-Man No Way Home.
Shuri is more fit to be in the lab, but she was forced to be the protector of Wakanda out of desperation.
What Ryan coogler did was admirable because he took a no-win situation and made a pretty good movie. Now, the lighting issue vastly affected the streaming re-watch value unless you have a BOMB ASS TV and/or know what settings bring out the best in the movie, but it was realistic. And if you saw it in the theater it was spectacular.
Think about real life. How many people do you know who have had someone, either the primary breadwinner or the matriarch or patriarch who is the glue of the family, die all of a sudden out of nowhere. People got to figure out how to pay bills, people got to figure out how to pay taxes, people got to figure out how to deal with life while life is coming on a train barreling towards you at 90 MPH. THAT was BP2. And she had to deal with a WAR with no powers and use science to recreate the herb
Namor and his people were formidable, Killmonger showing up was beautiful and unexpected, and aside from the Lesbian love that was inserted that no one needed/wanted/asked for the performances were spectacular - plus Little T'Challa at the end was a very nice touch.
While Shuri is ill-fit to hold the mantle long-term, she found out firsthand that heavy is the head who wears the crown.
There was no better option at the time considering how difficult it would have been to simply re-cast T'Challa, and it actually fit the comic. Replacing T'Challa is as impossible as attempting to replace MLK after his assassination. You needed a strong mind, strong character, willing and able to ignore the noise and crisicism with professionalism, able to do the character and the action and handle the newfound fame with people coming at him all over social media.
You needed a Jackie Robinson Black man RIGHT NOW, and those do not grow on trees.
With more time to scout and the cool down period of Chadwick's death, I believe that actor can be found
I can't wait to get this TV either this week or next to watch Wakanda Forever in all it's splendor as it was meant to be seen.
