You know, I'm starting to get the impression this thread is mostly you and I trying to one up each other in random View Askewniverse trivia
Not that I have an issue with it, I love talking about these films.
I think my favorite scene out of all six films, is Holden and Alyssa talking about events that happened in the previous two movies. Up until that point it wasn't really a shared universe. That movie solidified the fact and made it real.
And you are right on the money, going from the near dead seriousness of 'Chasing Amy' to the slightly out there "Dogma" and following that up with a live action cartoon then segueing into another extremely realistic film (Clerks II, nootch) and making it all still feel like the same universe. Pretty impressive.
