Fair point, that.
I hadn't even heard of Guardians of the Galaxy prior to the movie coming out, tbh. Though I wasn't super fond of GoG2 admittedly.
I don't really know enough about Eternals to have any expectation one way or another, but I will say that if nothing else the Shang Chi trailer impressed me a lot more than I expected.
Speaking of Iron Man being b-list... I confess that when the Iron Man movie first came out, I kind of brushed it off without even seeing the trailer until my dad basically forced me to watch it, being like "no, seriously, you need to see this"
Honestly I never really cared about Marvel heroes, other than Spiderman, prior to the MCU. My nerd cred, it is in tatters.
