I like the cosplay. Jamie Alexander is great as Sif, but I also think it's more interesting when someone finds a face for a character that isn't already established as that character (says the man using Michael Fassbender as Magneto <_< >_> )<br/><br/>If you go by this image, she actually does look pretty good as Sif.<br/><br/>(http://upload.wikimedia.org/wikipedia/en/6/6b/Sif.jpg)
