Yes yes by all godly mean yes.

I won't be surprised if you don't like it, but you should watch it anymattter. It is a classic and there are laser swords. Immediate win.

Obviously you should watch them in the order they were made. A New Hope, Empire Strikes Back, then Return of the Jedi.
While the prequals were only pretty okay, I would say watch them afterwards, because it gives more depth in the story. Mostly kinda.

Just watch them.
