Of course, some movies deserve a remake given the advances in production budgets, technology and special effects. The nearly iconic Godzilla is an obvious example of that. War of the Worlds, Planet of the Apes and The Time Machine were good for the same reason. Psycho remakes were good but originals do not need to be discarded, (it's hard to beat the original Norman). Remake of Steinbeck's Of Mice and Men (1990's) was excellent and In the Heat of the Night was good. The Thomas Crown Affair, Ocean's Eleven and The Italian Job were excellent as originals and their respective remakes were also notable. Some "remakes" from old television series to movies have been top notch. e.g., Mission Impossible, The Adams Family, Get Smart, The Saint, My Favorite Martian, The Avengers to name a few. Some TV shows from the 60's sucked back then and subsequently suck when made to movies, visa-vi: The Beverly Hillbillies.
I would go see a remake of The Great Escape but who could fill Steve McQuein's shoes or ride a motorcycle like that? Maybe Russell Crow?
