Again, a couple more ideas:
- when R2D2 shoots the lightsaber into the air, and Luke is waiting with his hand in the air for it, this could be shortened just a little bit, so it would seem even more synchronized, a real Jedi move.
Yeah I always thought if the saber could just fall short of Luke in front of him and he uses the Force to pull it in his hand in a clear Jedi move it would have been much better.
