Are Marvel Movies Too Formulaic?

Are different episodes from a single TV series formulaic? Because that's what MCU movies are, a different episode in a series. Granted, we're talking about grand episodes in a vast series but that still doesn't change the fact that they all probably want to be able to fit in nicely together if they don't want to end up with such a disjointed overall show.

Anyway to answer the question, no I don't think they're formulaic, at least no more so than your standard action-adventure blockbuster. I do think they follow a certain theme.
