Don't listen to the negative reviews

The plot isn't so bad, but the pace of storytelling is too slow which makes people bored. Certain moments are so obvious and unnecessary for the main plot. I would've fast-forwarded those moments if it was an online streaming. The ending looks like implying a sequel, not sure if this movie will get one

There are moments in this movie where the great movie it could've been peek out... They're fleeting, here, but they're worth savoring, and they happen often enough to make it worth your while.

True to its essence, the characters remain on the same line and manage to entertain the viewer, each highlighting their own distinctive qualities or touches.

Marilyn without the Strasbergs, without the Russian drama coach, without the Method, without the hours locked in her trailer shaking with stage fright. And it is her best ever acting job. This is the ONLY film that really taps into the 'off-kilter' and wounded quality of MM and uses it as an indispensable element of the movie. Elisha Cook's little turn as an elevator operator and his repartee with M.M. is a memorable minor moment and one of many such delights scattered throughout. I've heard that Richard Widmark was very nice to Marilyn and helpful on the set. Of course with 40 or 50 takes for even short scenes, a Billy Wilder can put up on the screen a dazzling Sugar Kane in Some Like It Hot but this is the real Marilyn not just her sheer 'luminescent beauty'. Even by the time she made Niagara, something was lost already, though she was very good in that.

Don't Bother to Knock is a solid film despite it being a slower film. Marilyn Monroe was terrific, playing an innocent, lonely girl who quickly turns into the maniac that she is. We get to see just how good of an actor she really was, instead of the sex symbol she was forced to be. Richard Widmark plays a relatively round character as a pilot, who starts out as a man without a heart but proves himself and his girlfriend that he does indeed care about others. The film was not a masterpiece in my eyes by any means, but for a 70 minute film, it was a memorable experience to see Monroe act with such strong emotion.Roy Ward Baker seemed to enjoy using establishing shots in this film, with the over the shoulder shot being used quite often when characters were having a discussion. Low-key lighting also added to the suspense, especially in the little girls room when Monroe was having her most sinister moments. He utilized medium close shots for her most vulnerable moments, such as the end when the realization is setting it. The editing definitely contributed in making it a solid experience, but Monroe is what really made the film work.

I was not looking forward to watching this movie because I have never been a fan of Marilyn Monroe. After watching it twice, I have to say I am so happy that I did watch it. It starts kind of slow, but once it gets going the craziness does not stop until the very end. From the very beginning, you can tell there's something that's just not right with Nell. Towards the middle, Jed gives me a really creepy vibe. Like, who just peeps in on some random person in a hotel room?! And the fact that Nell just went with it really kind of grossed me out. CREEPY!! Then, when she started going crazy on Bunny, I almost cried. The girl was so sweet and so innocent, I don't understand how anyone could do such terrible thing to a child like that. I know if I were her mother and walked into that scene, Nell probably wouldn't have been around to get dumped into the loony bin.

this movie is pretty good you don't expect Marilyn to be like this in a movie ever. I know people might be disappointed but at the same time its a shocker movie it's not bad it's pretty darn good for a Marilyn movie she plays a psychotic babysitter its hard to explain but you just have to see it for yourself to know. at the same time I feel bad for Marilyn throughout the film if like if you just woke up on the wrong side of the bed you got crazy and that's how it feels its a dark movie? I don't know maybe but if you want to see Marilyn play a suspenseful role this is a movie to check out. if you want something to get set up for this film watch Alfred Hitchcock's "Psycho" and "rear window" and yes those are both Alfred Hitchcock's films
