Less is always more in art.
Not necessarily true. There are definitely places where more is more.
Indeed. But, as I've said before, it's not how long a film
is - it's how long it
feels.
One of the best films I've ever seen is EUREKA (the 2000 Japanese film, not the Nicolas Roeg film), which runs for a Jacksonian (Peter, not Michael) 217 minutes (so Mr Maltin informs me), yet I do not begrudge it its whopping running time, and neither am I even really aware of its whopping running time, because it's just so gripping and amazing. Sure, it could probably have lost quite a bit of footage and still "worked".... but some films unfold with the profundity and power of great novels, so why cut 'em?
There are many great "long" films, and there are, of course, many films that are insufferable even at a lean 80 or 90 minutes. Horses for courses. Depends on the film.
