Here is my list of a top 50, as near as I could manage it.
To start off, these are the two movies I have loved that are most calculated to cause others to gasp at my poor taste. Guilty pleasures, I guess.
1. Portrait of Jennie -
Much of the dialogue makes even me wince today, but it combines the supernatural and time travel in a way that is poignant and haunting to me. I would love to see a good re-filming with no cliche’ characters or dialogue and a moody, low-key script. Much the same can be said for my second choice,
2. The Ghost and Mrs. Muir -
Very corny and calculated and hardly a story at all since the ending can be seen a mile away. But there is a wonderful scene of the ghost’s farewell speech, to me one of the finest scenes in the history of old Hollywood. I love the subtle directorial touches that suggest the presence of the ghost in the scenes after his farewell. Also has a great Bernard Herrmann music score.
Next, here are favorite movies that almost are no longer that because I have seen them so many times I am almost sick of them.

3. How Green Was My Valley
4. Shane
5. Alien
6. Psycho
And the rest in a very random order, including ‘boy movies’ I have listed on another thread and those from the ABC top hundred which I agree with. A bit of a mixed bag.
