For me the worst part was when Rose and Finn were captured standing right next to Phasma and then that big explosion happens and everyone around them is dead while they are completely unharmed. Phasma is gone only to appear from a completely different section of the hangar as if nothing happened. WTF? The explosion happened right on top of all of them standing a few feet apart and then suddenly Phasma appears with a bunch of Stormtroopers like 300 feet away.
