There's no need for this silliness. I've just been on another website which allows comments and the aggression there was pitiful to see. Let's talk nicely.
I for one have no problem with the appearance of film-Théoden. To me, Bernard Hill was a perfectly fine old man to play the part. I would have thought that, out of everyone, it would be our older Downers who saw such differences in age.
The issue of Frodo's age (as well as his differences in age with the other hobbits) seems like a more interesting topic.
There are far more annoying things about the films. Even if I loved every part of the films, though, I wouldn't mind one bit about Théoden's 'youth'.
