I've seen the first one, pretty dissappointing.
My thoughts. To me it seemed they were desperately looking for a "last-stand" scenario and completely exaggerated it. I mean, the defenders are holding the castle against those vikings with like 15 men or so. And at the end, the day is saved by the French, really?
Don't go mad, s'il vous plait
EDIT: As it happens, I'm currently watching American Horror Story and when I rewatched the Ironclad trailer from OP it struck me that that Lady (dunno her name, it'S like the only female role in Ironclad) is played by the very same actress who plays that freaked-out girlfriend in Season one of AHS...
