Over the past few months I've watched every remaining film from the imdb top 250 film list, I've watched tons of films, some silent films as old as the 1930's and I've watched my fair share of old films before this but I will say that I believe that Sci-fi which is dependent upon effects generally ages quite poorly but Sci-fi who's main saving grace is it's plot or just regular dramas/thriller age far better simply because a good plot doesn't really age. Granted in the grand scheme of old films I much prefer films from say the 1970's onward at least because I think film stories really started to peak.
