I don't think we need to have everything be explained explicitly throughout the movie.

No. What's IN THE MOVIE is never enough.

We see a variable strength DS laser, that's a load of hogwash. We need someone to lean into frame and say "Goodness! The Death Star fired on the ship at lower power, hence the obvious lower power shot!"

I can't just SEE Vader on his Star Destroyer, I need to see him in transit, and frankly, it would have helped if there was someone on screen commenting on it like "It sure is great Vader left Cloud City to arrive here on this Star Destroyer."

I can't imagine any fans having issue with a character like that.
