In canon, when Dumbledore and Voldemort fought in Order of the Pheonix, they weren’t just launching high level spells like missiles, they were apparating around and manipulating the landscape around them. On one occasion, Dumbledore has Fawkes catch an Avada Kedavra for him (reducing him to a chick,) and I believe he may also have blocked another with an animated statue (although that might have been a different spell.)
I was extremely disappointed that the movie adaptation reduced their confrontation to a highly pyrotechnic instance of magical arm wrestling. J. K. Rowling may not have thought all her ideas out properly, but at least she managed to show that when wizards of Dumbledore and Voldemort’s caliber duel, they get creative.
Suddenly Quirrell’s using it in the duel with Bahry is looking a lot weirder. What happens when he dodges it, does it go straight through the wall and keep on going indefinitely until it hits someone? Isn’t that a massive liability since he risks someone seeing it, thereby giving away his presence?
Being able to be blocked by inanimate objects might seem “lame” for an epic forbidden spell, but being able to pass through solid matter like a jet of neutrinos turns it into yet another game-breakingly borkable element like the Bag of Holding. Combined with the Eye of Vance, Moody should mostly be able to avoid dueling in favor of sniping dark wizards through buildings.
This seems like an uncharacteristic failure by EY to think things through.
