She had very good dramatic roles (IMO) in Don't Bother to Knock, Bus Stop and Misfits.
Thanks for the recommendations. I've seen
"Bus Stop" and
"The Misfits". That reminds me, I neglected to mention another problem I have with a lot of Monroe movies is that she rarely has a male co-star who I find to be her equal (in terms of the quality of his character). For most of the movie, I found the guy courting her in
"Bus Stop" to be insufferable. It made sense from a story perspective since he was supposed to be someone very naive as a man who wasn't very worldly, but it still made their 'courtship' often very frustrating to watch.
She really nailed the last scene, though, when he FINALLY came to his senses a bit and showed some maturity (I would have liked that to happen earlier, though). I think scenes like that really showed her dramatic potential. I thought
"The Misfits" was kind of a mess, but again, it wasn't really her fault. It was very overwritten (understandably since it was written by a playwright in an apparent moment of excess) and all of the characters including hers were unfocused and hard to understand.
It also has some of the most sickening animal cruelty I've ever seen in a movie.

Again, Marilyn did a good job playing a more dramatic character, but it was hard to be engaged by her character or any other in that movie since the writing was so scatter shot. I will definitely check out
"Don't Bother to Knock" at some point. I hope it's more tightly written than those others.
In my search for the perfect Marilyn movie, what has constantly alluded me is a script that gives her a male lead who is a fully formed three-dimensional character and isn't gratingly shallow, clownish, naive, or manipulative. I heard
"Niagara" fits the bill, but I've been reluctant to check out a movie where she's supposedly more of a femme fatale. I just like happy-go-lucky Marilyn too much.
