Based on the first film and what I read of the second film, the problem with the Webb franchise seems to be that it's too fixated on setting up things for the future than on the story at hand. Both films seem to get the criticism of the universe buildup taking away from the character development and story progression, or at least from the full potential of those things being developed.
I haven't seen TASM 2 yet, but I really hope that's not the case. If it is, I will be really disappointed. These things drive me nuts. It's the same issue I took with MOS and most of Marvel's Phase 1. This is not television. I should not have to wait a few years to see things that should have been covered in the first film. You can still build a universe and set things up for the sequel(s) while still telling a complete self-contained story. You have to find that balance. Examples of films that found that balance are Batman Begins, The Dark Knight, Iron Man, Marvel's Phase 2 (I took issue with IM3 and Thor 2 but they're still self-contained), etc. Even First Class has that balance there, despite all the continuity errors.
