The family is great! Don't worry if the movie seems disjointed at first, Jaime's family only gets more central to the movie in the back half (which is also where you find a lot of the fun stuff that doesn't make it into the trailer).
Susan Sarandon's villain worked better than I expected - I could go into detail but I doubt anyone wants to hear that from me.
The symbiote thing isn't explored a whole lot but that's absolutely the right move, that sort of thing needs its own movie.
It's not my favorite superhero film (Ant-Man and the Wasp) or the movie I enjoyed the most this year (Ruby Gillman) but Jaime is still my favorite superhero and I'm glad I don't have to explain who he is to people anymore! I hope we can see more of these characters now that we're past the origin story heavy lifting.
