Hey, there´s isn´t a Hollywood war movie were archers doesn´t kick the ass out of everybody. Even the Spartans in 300 got killed by archers.
Though most of the times the archers will just kill a shitload of people but once the enemy gets to melee distance there still appears to be just as many of them left, and the archers were just there for their awesome coolness (all LOTR movies, Gladiator, Troy, Attila, King Arthur, Braveheart, Kingdom of Heaven, etc).
