In reply to Colin Gourlay.

That's a good point, and usually is a deal-breaker for me. But I didn't personally have any issue with it in this movie, and actually thought it was charming. Maybe since, as you say, the entire sequence showed how it was still easily capable of wiping out the entire party, and the best they'd be able to do would be to escape from it. Or possibly it's that I haven't played enough D&D to think of dragons as sentient creatures, so I still think of them as monsters. Whatever the case, for me (and maybe just for me), only one line of dialogue ("did he eat the whole hoard?" or similar) stood out, and none of the rest like it was making fun of fat people.
