Look at some of the top grossing films, Titanic, Star Wars, ET, LOTR, Spider-Man. Top grossing movies that got pretty good reviews. Yes, and I 'm aware originally that Star Wars had mixed reviews, however SW is an exception to movies that had people completely change their minds, days, months, years later.
And BW, most movies are fiction.
In all fairness though we've seen where fan opinions on Titanic have gone...and few people think that movie is anything special anymore
ET has a place in pop-culture, but its an iffy one, like its there and we all acknowledge the fact it was a interesting movie at the time, but (imo) I think it has aged poorly, just my opinion on pop-culture
Spider-man people where ready to jump all over that at the sight of trouble with 3, when in all reality it is no where near as bad as some people make it out to be (much like, again imo the pirates sequels), not as good as the first two, but if that is the low point in a franchise, i'll take that anywhere
LOTR, time will tell, my personal analysis on how the franchise has settled into pop-culture is by the fact people are so ready to make fun of the "gayness" of sam and frodo....and then....not much after that, me at least I don't hear really anything in any form of popculture that allueds to LOTR (with the exception of Clerks 2 which pretty much did nothing but bash the flick: and gave it a sweet ending lol)
Star Wars, it is the exception, but lets say for instance if Pirates had been the first franchise to really blow people away with special effects, do you think the reviews might change with time?
The first Star Wars movie, yes opened with intially mixed reviews but it was so unique, and people loved it so much that imo (i wasn't there so i don't know for sure but this is really the only reason I can see for critics to completely change their opinion) the complete originality of it literally forced critics to change their opinions.
I guess I don't think critics opinions will change for Pirates, I do think fanbut I guess the question I pose to you is if Pirates where the first do you think that would be the one to have critics opinions change???
I don't know if it would or not I'm just saying Star Wars does put a ceiling on how high blockbusters are judged, so its not always Pirates gets a 7/10 its that it gets a 5/Star Wars
