Star Wars has always had explosions and sound in space (it is Space Fantasy not Science Fiction) but even in evoking the dreaded science bit here, these are ships filled with breathable air, surrounded by force fields and venting breathable air, couple that with the possibility that the ships may be built with elements that don't need atmospheric Oxygen to burn (like some metals) what is TOO unrealistic about them being on fire?

If it works with the story and can be done well it should be done.

Well I know that theoretically you could have explosions because of the oxygen in the ships, but most of the explosions are quick, as there isn't enough oxygen to support a long, sustained explosion.

I think there is a difference in that and having a ship be continously on fire. Maybe if it was a small fire within the shield, but a large fire continuously engulfing a whole ship would look a little out of place IMO.
