I’m sure everyone here has made good points as why you shouldn’t watch them - but if you go in expecting a decent Sci-Fi action flick, you might actually enjoy them. Don’t go in expecting to feel the same magic you felt when watching ANH for the first time. Expect to be slightly thrilled, mostly underwhelmed, and be prepared to scratch your head in confusion… a lot.
…so why bother if the best case scenario is “slightly thrilled, mostly underwhelmed”?
If anything, watch the films in 5.1, and disable the center channel. That way you hear the most important part of the prequels - their exceptional soundtracks.
Or I could just listen to the soundtracks.
