These films are about a Galactic Civil war.

They are fun for us because they are exciting and the characters are engaging.

Once again I refer to the briefing in ANH.

The pilots look worried, Han frequently shows signs of disbelief at what he is hearing.

It's all very pessimistic.

This makes the final battle more intense, more emotionally realistic and more enjoyably exciting for the audience.

If the situation is less tangible and the characters can't be bothered to take things seriously why should we?

This makes the pay off to the action less exciting, cinematically it malfunctions.

Is it against the rules to randomly quote for truth? I might have necro-quoted as well. Oh dear.
