Answer:
Honestly i would say all of them because special effects can embellish one's point and add dramatic flair to influence the message. Lighting can express what scene, mood, or tone is going on. Music flourishes the emotion or feelings that are supposed to be felt. Camera angles are used to help enhance the narrative, the theme, and the overall mood. And audio effects are especially helpful when making music but adds realistic but also quality effects.
(that was not very helpful but that's my opinion i guess haha)
