I enjoyed what we got with the Illuminati. They were there to show alternative/variants of characters already established, introduce F4, X Men and Inhumans into the MCU, drop exposition and the concept of incurgence, and showcase Wanda's powers.
They were arrogant, coky and cold and underestimated Wanda's powers and once she wiped the floor with Black Bolt and Mr Fantastic Captain Carter and Captain Marvel lasted as long because they teamed up.
It didn't help that the smartest man alive gave Wanda Black Bolt main strength and she used her powers to take him out with ease. His death was the most brutal. Followed by Carters.
Reed Richard head poping like a ballon was golden and I could watch that all day.
Xavier was there as a tribute, nostalgia, introduce XMen concept into the MCU and strike a blow with his death...for a 3rd time. My inner child was happy hearing the theme to the X Men theme songs.
I was expecting and wanted more cameos but in restropect am happy with what we got. Otherwise it would have diluted the film. Only other place I can see other characters make an appearance is when Strange and Chavez are traveling the multiverse.
Perhaps we will see more in deleted scenes or extended cut if Marvel gives Raimi a proper release full of goodies like Sony did with his Spider Man films. *fingers crossed*
Do you guys think the FF movie will possibly take place in the universe that Reed is from (and be a prequel to Multiverse of Madness) ?
I feel like we will see that Kang trapped them in an alternate reality or the quantum realm because they were a threat to him. Perhaps we will see them next in Quantumania.
