Still, he doesn't look like a Jedi. It is a consistency issue. And yes, Luke was that good because he defeated Vader later in the movie. You guys would say that Luke in ROTJ is about the same as Anakin in AOTC. Right? Yoda is the best in the business, Luke should be close by then. He was trained a little from Obi-Wan to.
It shouldn't be about how good Luke was guys, the battle is lame compared to every other battle in these movies. We should see more in space rather than a dragged out SB battle. It should be harder for Lando to even get in the DS. Ani and Obi in ROTS didn't just fly into Greivous's ship. There is more to show in space and less to see on the SB.
