Of course! A good film is a good film regardless of age. If you're looking for one to watch I recommend The Godfather films. The first and second are flawless!
No, I know its shallow but the crappy video quality immediately turns me off to a movie
Sometimes it's just too hard to see past the black-and-white or the grainy colors, and the usually bad quality ...but I'll watch some of the movies listed!
Mostly the classics, because I'd feel like an idiot if somebody was talking about The Godfather for example and I had no idea what it is about.
Not sure what exactly is an "old movie" for you, but I really love 12 Angry Men, The Apartment and Rosemary's Baby. Also Rocky Horror Picture Show is awesome.
Finished Rebel Without a Cause and East of Eden...both great movies I didn't expect them to be good at all since they were old but I have a newly-found appreciation for old films!
I'm deciding between Casablanca, The Bicycle Thief (the Italian movie), or Citizen Kane
...but I'll watch some of the movies listed!
But yes, occasionally I'll watch an older film or two. One of my favorite Tv shows is a show from the 60s/70s.
