Fireworks are impressive to watch from behind the castle. It's a completely different experience and you do not see any of the projections on the castle so I never suggest that location for the only time you have to watch them. But if you are ok with missing the stuff on the castle then watching them from the back is unlike nothing else. It puts you smack in the middle of the fireworks with them going off around you in 360°. I just happened to be back there as they began on one trip and it was so incredible we now make a point to watch them back there each trip.
