I prefer the Prequels.
It has many nostalgic feelings to me, because i grew up with them.
The story is really interesting and has cool characters.
But in the cinema of Episode 3 i was disappointed.
Because i hoped to see a lot of masked Darth Vader.

With the Sequels i have many problems.
Also the EP7 disappointed me heavily.
I was very fixed on the expanded universe and hoped to see a powerful Luke with the new jedi order on Yavin IV.
Instead we get a weak Luke to see.
For me make the stories of the suequels no sense and they are not canon to me.
Next problem is, that the story is not from George Lucas.
He’s the father of Star Wars and has to me the highest priority, but Lucas plans for EP7 were trashed.
Another problem is that Rey is a Mary Sue, she know how to use the force and is heavily good in the lightsaberfights, so the training in EP8 by luke make also no sense.
Also the Sequels doesn’t feel like that i watch Star Wars.

The Original Trilogy is unbeatable.
