I think that the Alderaan explosion was the one most in need of an update, but the one they gave it did little to make it better. If it was just the larger explosion it would have been fine, but they gave it the praxis shockwave, which just made it look dumb.
I think it would’ve been a better idea to only add the shockwave effect to the Death Star explosion, making it more epic compared to the Alderaan explosion. Save the gimmick for the grand finale.
