Just for fun, and some perspective, let's remember that this movie is a solo hero origin, something that is slave to probably the most well-worn and limiting formula in the genre (and just about any genre, outside of rom-coms, lol), certainly more so than the sequels and group films. So let's look at how it's faring against Marvel's other solo hero origins:
1.) Black Panther (97%) - which I feel barely counts here since we got to know him and he had a whole arc in a previous film before it.
2.) Iron Man (93%)
3.) Doctor Strange (89%)
4.) Captain Marvel (83%) - for now, obviously
5.) Ant-Man (82%)
6.) Captain America: The First Avenger (80%)
7.) Thor (77%)
8.) The Incredible Hulk (67%)
It's in a perfectly good place, imo, especially when the difference between 10 percentage points on RT hardly means anything when watching the actual products - hell, I enjoy all those other origins below Doctor Strange, minus TIH (and this film, obviously since I haven't seen it yet), more than Doctor Strange.
