Ant-Man and the Wasp: Quantumania

I was really excited for Ant-Man and the Wasp: Quantumania because I enjoyed Ant-Man and Ant-Man and the Wasp so much.  I went to see it last night but, unfortunately, I thought it was a mixed bag.  After the events of Avengers: Endgame, Cassie Lang (Kathryn Newton) builds a device that can make contact with the Quantum Realm but it accidentally opens a portal which transports her, Scott Lang/ Ant-Man (Paul Rudd), Hope van Dyne/ Wasp (Evangeline Lilly), Hank Pym (Michael Douglas), and Janet van Dyne (Michelle Pfeiffer) there.  They discover a world filled with fantastical beings and creatures but they also discover a time-traveling multiversal being known as Kang the Conqueror (Jonathan Majors) who was exiled there and then betrayed by Janet.  Kang is now the ruthless dictator of the Quantum Realm and demands that Scott help him rebuild the multiversal power core that Janet destroyed.  This leads to an epic battle where the fate of both the Quantum Realm and the Multiverse hangs in the balance.  What I loved most about the first two movies in this trilogy is the lighthearted and goofy banter between Ant-Man and his crew so I was really disappointed to find that missing in this installment (where is Luis?).  Much of the humor in the interactions between Scott and the natives doesn't really land and, in my opinion, the characters Lord Krylar (Bill Murray) and M.O.D.O.K. (Corey Stoll) are pointless and ridiculous, respectively.  The emotional core of this movie is meant to come from the father-daughter relationship between Scott and Cassie (Hope is completely sidelined) but I just wasn't very invested in it because I didn't like Cassie as a character (I'm not sure if it is because of Newton's portrayal or my growing annoyance with the plucky-teenager-who-knows-better-than-everyone-else trope).  The CGI is both messy (it is obvious that everyone is acting in front of a green screen) and exhausting (I found my mind wandering during the never-ending climactic battle).  Having said all of that, I absolutely loved the character Kang and Majors' portrayal of him is brilliant because he is so menacing but also a bit vulnerable.  I found Kang's interactions with Janet (Pfeiffer is also outstanding) to be the most compelling aspect of this movie and I am actually looking forward to seeing more from him moving forward (definitely stay for the mid- and end-credits scenes).  I didn't hate this because it sets up one of the most interesting villains in the MCU but yikes!
