What is a classic movie most people have seen and you haven't?

In today's world you can certainly find out enough to know whether those movies would do anything for you, if you can avoid having them completely spoiled. Personally, I liked Titanic and Good Will Hunting even though they were mainly pitched to people your age or even younger and I was in my 30's and 40's. Titanic is a story that always moved me any way, the spectacle they produced on the screen enhanced the "big themes" of the tragedy of hubris and the triumph of love. Good Will Hunting has two gorgeous young lovers, a clever screenplay, and Robin Williams at his peak. What more does anyone need?

Yes, people will tell you those movies are amazing and others will tell you they are nostalgic garbage. However; NOBODY's opinion is more relevant than your own. If you get the opportunity to watch them, do it. One of those movies should leave you with a positive impact that would be well worth it. If not, than you know what films to avoid.

I have never seen any Harry Potter films

I've never seen The Godfather or Rocky

Ive actually watched all of those. I've been ignoring the new super hero movies lately however. I find that they're becoming quite the overkill recently especially with Marvel.

the godfather and good will hunting

Not a single movie based on Marvel or DC comics. Except for Catwoman and Constantine, if those count at all...

I have never seen any of the Soprano movies

Of those, I'd say Good Will Hunting is worth seeing. I haven't seen Titanic either, and don't feel like I've missed anything.

Forest Gump

I've never watched any of the terminator movies or the matrix. I'm sure there are others that I could mention but those are the first ones that leap to mind.
