So I just finished watching the movies again. I saw a lot of the characters in the game, but also didn't see a lot of the characters. Keep in mind I've never read the books *gasp* so my opinions may be moot.
Some notes on the ones I saw.
Eowyn - She was certainly strong-willed, but also a fairly capable fighter. Seems to me she could have been afforded a 2 attack at least.
Denethor - While I like his card and the actor (John Noble is one of my current favorites), I really didn't like the character. There wasn't much "heroic" about him. And he certainly didn't possess the knowledge necessary to be a Lore hero IMO.
I know we're still waiting on a Boromir, Frodo, and Sam for heroes, but how about Theodin? I saw more of him than of any other dwarf, ie Gloin, Thalin. Speaking of dwarves, I assume they are a bigger part of the book than "Gimli son of Gloin"? As far as the movie showed, dwarves are extinct except for Gimli. Also, what was the name of the blond elf that came to Helm's Deep? I couldn't tell if they gave him a name. He could probably get cardboard form too.
So the heroes that do not appear in the movies afaik are Gloin, Thalin, Glorfindel, Beravor, Dunhere, and Elenor. Theodred was in for about 2 minutes but he was already dead.
