. A Superman movie is definately something that I'd watch (even if its just out of morbid curiosity to see what they did to Superman). Amy Adams movies are mostly not, but a lot of them aren't really normal movies anyway.
Your Superman "experience" seems very limited.
The films you listed are mostly genre films and therefore are not "normal" movies. Amy Adams credits are probably a lot more "normal" than you think.
Well, I seem to have a few people that agree that she's not a household name, so there is that. As for my superman experience, here's basically what I can recall seeing/reading involving Superman
TV/Direct to DVD movies:
All of Superman TAS
All of Justice League
All of Smallville
A few episodes of the old Black and White Superman
A few episodes of Lois & Clark
Every DC Direct Animated movie with him except The Dark Knight Returns
Movies:
Superman 1 & 2, and good portions of 3 &4
Superman Returns
Comics:
About 25-30 issues of Silver age superman (from various DC Showcase collections)
Some Golden Age Superman stories
All of the JMS started "Grounded" arc before the reboot
The first six issues of All Star Superman
Various issues of Action comics
A lot of Justice League comics
A lot of various event comics and misc appearances, way too many to list
I'd say that, in general, I have a good amount of experience with Superman.
