Wow, you are a real fan I guess. The spin off Rogue One was very good I must say. Han Solo movie I have not seen yet. Is it as good? What I remember from part I (but I haven't seen it in a long long time) is that irritating Jar Jar Binks. However part II and III were better again as I remember.
By the way, don't know if you are a Harry Potter fan (I am not although I like the books and movies) but the Fantastic Beasts movies are very good!
Well, there is a biig theory behing Jar Jar, as you know, épisodes I II and III have been made after the other, so, George Lucas decided to put characters quite important which would explain the other épisodes (IV V and VI).
So, this means that every single character was thought and very important, many people, like you, Don't like Jar Jar because too stupid… too… Strange ect..
You can see many importants things which I will explain you and maybe you will start seeing SW in another way
Remember episode III
Palpatine explains the tragedy of "Darth Plagueis the Wise", a Sith Lord who had won the death but who was killed by his apprentice… he says it like if he had lived the story… what if he was the apprentice who killed Darth Plagueis?
Admitting what he said is true, it would mean that he didn't kill him, or at least that Plagueis didn't die true?
Now the interesting part of the theory is coming, Jar Jar is Darth Plagueis, he is the true Dark Lord of the Sith !!!!!!!
YOu Don't Believe me right now and think I'm a really crazy boy who is just saying randoms things, but here I will prove it :
1) YOu feeling about Jar Jar is that he is stupid, so, explain me how a stupid guy became Senator? Maybe using the Force ?
2) In episode III, who suggests to give full powers to Palpatine? Jar Jar and this, allowed Palpatine to became emperor !
3) If you see in episode II, you can note that he is Moving his mouth while some other characters like Padme are talking, would it be a mistake of effects or is it what George wanted and in this case, it would mean that he is making saying to other characters what he wants?
4) In episode I, Jar Jar and some other characters are eating to Anakin's home and Jar Jar is like provocing Qui Gon to test his reflex, maybe because of this he informed Darth Maul and that's how Darth Maul killed Qui Gonn (SPOILER ALERT)
Now, did your opinion of Jar Jar changed? Or do you think I'm still a crazy boy?
About your question, I watched the Harry Potter saga, but sadly you can't talk as much about those films than you can do with Star Wars.
The Han Solo spin off is really great, full of Easter Eggs, a few disappointing things but globaly great, a film to Watch.
