Keep in mind there are several cuts of the film.

I like the final cut but it lacks the inner monologue voice over of Ford that explains certain things about the world. You may want to watch the Theatrical or International (same as Theatrical but more violent scenes included) version the first time. Avoid the Director's Cut as it's actually the Work Cut with key pieces of the film missing and Scott had NOTHING to do with it. The Final Cut is the real Director's Cut with Scott backing it and the one I recommend you watch mainly.
You can rent the Theatrical version on YouTube or GooglePlay for $2.99.
