Cappin marvel and photon are both dull, uninteresting characters, they have been in all the mcu outings they've been in, from the movies to wandavision. Kamela khan by all accounts is the best thing in it, but the character doesnt appeal to me, same as any of the 'young avengers' - I'm not the demographic (suppose that makes me ageist or something though..)
As to the story, spaceballs: the girls get it done edition? From what ive seen, the interaction between the characters lacks anything that can be considered remotely satisfying, the villain is a female Ronan (yawn, been there done that), the story is disjointed and has been done better, many times over.
