Eh, honestly, if stuff like this is going to ruin the movie for you, I honestly feel sorry for you.
Sure, even fictional universes need rules to their "magic" (otherwise, Harry could just send the magical equivalent of an intercontinental ballistic missile halfway through the fifth book to take down Voldemort for good). But it's where these rules are drawn that can get a little fuzzy. All I know is, earlier this month, I managed to suspend my disbelief to a level I felt comfortable with so I could enjoy my movie about space wizards. Star Wars, man! It's kind of sad that some people were apparently denied that, because of what they found acceptable for suspension of disbelief.
And honestly, I love debates on lore like this, I find them absolutely fascinating. But to hate the entire movie because of it? Again, I just feel bad for those people.
