Just one?
Well, to prove age has nothing to do with why I see Blade Runner's faults, I'll go with something older: Alfred Hitchcock's NOTORIOUS from 1946. Absolutely flawless film-making with a script sharp enough to cut diamonds.
But if you're looking for something more modern, I'll go with 2011's TAKE SHELTER. What a masterpiece that is.
Or you can look left at my avatar.
Haven't seen Take Shelter. Let's hope it does better on DVD sales than it did in theaters. Almost five million to make and not quite four in total worldwide box office? Ouch.
As far as any of Hitchcock's films, there are some I like, some I hate and some I'm indifferent to. For me, Notorious falls into the "meh" category. It's all a matter of opinion, right?
