Ok im going to post the rules again:
1. Please leave a brief description of the story, how good the acting was and if possible leave a short clip of a preview.
2. Please limit your suggestions from recent films as they havnt stood the test of time.
3. One suggestion per post.
4. Explain why its the best film you have seen
5. Use proper use of grammar and punctuation where possible.
I don't mean to be picky, but you wrote "Use proper use of grammar and punctuation where possible" and about you wrote "its" when it should have been "it's" and on the 2nd point you wrote "havnt" instead of "haven't" and also wrote "from" instead of "to".
Anyway, what's is the point in one suggestion per post? Because then it will just spam the page.
The test of time means nothing because it's whether in your opinion it is the best film you've seen, whether it's a year old or thirty years old.
Another idea would be that the video clips are links and not embedded as that would clog up the page.
