I own two PF statues. Daredevil and Captain America. Daredevil became my favorite comic character of all time. I thought his run from "98 to the end of Shadowland was the greatest run of all time. I needed to own some DD stuff and the PF captures DD perfectly for me. My second PF is Captain America. I love reading the World War 2 comics about him. My favorite time period in history with an awesome super hero. His WW2 attire, his comics, his two solo movie all factored into my decision to get his PF.
Before reading Daredevil I never would have bought his PF. If I didn't have such a liking to WW2 I never would have bought Caps PF. I only buy statues where I have a great like for the character.
I am thinking about getting some other PFs such as Thor, but I never really read any of his comics. I don't have a liking for him, he is just another superhero to me. It looks cool, but since I don't have that connection with Thor as I do the other two..... I probably will pass on it. Another one is the PF comic Superman. That is the quintessential Superman collectible in my eyes. It is perfect. I love that PF. But, I am not a big Superman fan. Never read the comics, hated MoS and the Reeves movies. My only connection to Superman is the Justice League show I used to watch. Not enough to make me buy it, even though I think it is the best Superman piece and possibly SSC best PF.
I don't why people buy something because it looks cool. Seems like you are trying to impress someone, impulse buying, or don't know what pieces you really love to blindly buy a character with no knowledge or connection to them.
