How do you people justify like the second of the two great trilogies best?

Rating: Null/10 (9 May 2014)

When I read these reviews, of Indiana Jones, and Star wars as well, I'm always amazed.
Where does this opinion come from? That Empire, or Temple are the best?
Raiders of the Lost Ark is clearly the best, and Star Wars Is clearly the best.
Maybe this is the opinion of the younger folks, who don't have the experience of seeing these films when they came out, how mind blowing Star Wars was, a total game changer, or how surprising and funny Ark was...maybe you just don't know how these films excited us, changed all we thought about film...how they became part of our cultural reference, or currency.
In both cases the sequels went steadily downhill, becoming more self referential, jokey, formulaic. predictable.
