McGonagall and Snape Duel

After returning to Hogwarts through secret passageway and confronting Snape about the true nature of Dumbledore's death in the Great Hall, Harry's being threathened as Snape pulls his wand. However after hearing the terrible truth, Mcgonagal managed to quickly push Harry out of the way and decided to face Snape on her own. Although not exactly accurate to the book, this scene is really well captured and packed with lots of small details (e.g. Snape deflecting Minerva's spells, purposefully taking out two death eaters in the process, taking their wands and avoiding the fight with his old friend by flying away).
