well, this brings us to a little tangent, but: this is the problem with that argument. says who? people who like comics? "kids and adults" love it? so everyone? i'm going to walk into the street and not find one person that's like, "superheroes? eh...."?
personally, just my opinion, but i couldn't care less about any of them right now. i get there are people that will line up at midnight for thor 955 or whatever, but you could say that about most things. it seems fairly obvious that the genre is headed for a tipping point. the market is so saturated, and will continue to be. but that's not the reason why they shouldn't bring this kind of IP into epcot.
a lot of this stuff doesn't make for very sturdy fodder for permanent attractions to be built on, especially when thematically, they don't make a lick of sense. i loved he-man as a kid in the '80s. where was my masters of the universe overlay on horizons? it sounds like something i would have pitched to my parents when i was five and they would have smiled, and said, "well, that's not really what epcot is about, sweetie." i guess we need to start talking to iger and co. (and the people who defend these idiotic decisions on these boards) like they're five-year olds.
so guardians had a great box office two years ago. will people still care in 10 years? will people care in five years when they open this? do people care now?
and everyone who says, "it's not feasible to keep upgrading based on 'the future.'" really? so you're telling me that 10 years from now, GotG is going to be so red-hot that this attraction won't feel outdated?
if you're talking yourself into this being good, it's because WDW fans have essentially fallen into an abusive relationship with these parks. things are so bad that when even one little thing is added (bathroom, smells to PotC), we lose our minds and say, "they're restoring it to its proper glory!" they're not. they're doing as little as they can so the profits are bigger than ever.
