My 2017 opinion:

Star Wars: 10/10

What can I say? Perfect movie

Empire Strikes Back: 9.5/10

The Yoda parts get boring. There, I said it.

Return of the Jedi: 9/10

Ford and Fisher mail in their performances. Hamill is great. The Emperor is menacing and awesone.

The Force Awakens: 7/10

Feels like Star Wars. The first half is 8.5/10, the second is 5.5/ 10

Revenge of the Sith: 6.5/10

I like Hayden Christensen in this for some reason. Dialogue is bad of course, but he tries.

TPM: 5/10
AOTC: 4/10
