Your remark doesn't make a helluva lot of sense to me. You admit she played the part of Mattie Ross to perfection but say you can't stand her.
I thought just about everyone in the film turned in great, or at least good performances, including Glenn Campbell. In fact, I think Duvall as Lucky Ned Pepper should have received an Oscar for Best Supporting Actor.
I may be right or wrong but, I think what the Lt is trying to say is, that he had no problem with the character and how it was portrayed, but that he just can't stand who played that character. Same as me, I can't stand the actress-no I don't hate-I just can't stand her. Same thing could be said about me for the likes of george cLOONEY. But that's a different story and for other reasons.
If im wrong, then I apologize.
PS, I used to think the same way about a few other actors and actresses. For instance, I used to not care much for Eli Wallach, Barbara Stanwyck, James Cagney and Humphrey Bogart. However, every one of these actors and actresses, are among my favorites now-and those who know mw-know that James Cagney is another one of my all-time most favorites. I can watch him as much as I can watch Duke.
Not to sidetrack too much but, one of my all-time most favorite lines from Cagney was from: The Fighting 69th. It was: "Take your hands off me you son of a Banshee or i'll knock your teeth down your throat." For many years, I thought the word Banshee was actually one of the words from the curse: SOB-because of the way he sounded when he said it.
