Good response, thanks I had forgotten that First Class was a reboot of sorts, which makes it easier to have the dividing point at Iron Man. Why Ghost Rider as the end of the "Great Power" era? There's FF: Silver Surfer and Spiderman 3 that same year which, imo, should belong in that same grouping. Spiderman 3 is also the last one before Iron Man. @Valryk I think Avengers may be less of a superhero inflection point and more of a movies in general one. It showed that cinematic universes could be very successful and we're seeing a number of studios attempt similar things outside of the superhero genre.
